module Applicative : sig ... end
module Applicative_intf : sig ... end

Applicatives model computations in which values computed by subcomputations cannot affect what subsequent computations will take place. Relative to monads, this restriction takes power away from the user of the interface and gives it to the implementation. In particular, because the structure of the entire computation is known, one can augment its definition with some description of that structure.

module Array : sig ... end
module Avltree : sig ... end

A low-level, mutable AVL tree.

module Backtrace : sig ... end

Dealing with stack backtraces.

module Binary_searchable : sig ... end

See Binary_searchable_intf.

module Binary_searchable_intf : sig ... end

Module types for a binary_search function for a sequence, and functors for building binary_search functions.

module Blit : sig ... end

See Blit_intf for documentation.

module Blit_intf : sig ... end

Standard type for blit functions, and reusable code for validating blit arguments.

module Bool : sig ... end
module Buffer : sig ... end
module Char : sig ... end

Character operations.

module Commutative_group : sig ... end

A signature for a commutative group (in the group-theory sense).

module Comparable : sig ... end
module Comparable_intf : sig ... end
module Comparator : sig ... end

A type-indexed value that allows one to compare (and for generating error messages, serialize) values of the type in question.

module Container : sig ... end
module Container_intf : sig ... end

This file has generic signatures for container data structures, with standard functions (iter, fold, exists, for_all, ...) that one would expect to find in any container. The idea is to include Container.S0 or Container.S1 in the signature for every container-like data structure (Array, List, String, ...) to ensure a consistent interface.

module Either : sig ... end
module Either_intf : sig ... end

Many functions in Either focus on just one constructor. The Focused signature abstracts over which constructor is the focus. To use these functions, use the First or Second modules in S.

module Equal : sig ... end

This module defines signatures that are to be included in other signatures to ensure a consistent interface to equal functions. There is a signature (S, S1, S2, S3) for each arity of type. Usage looks like:

module Error : sig ... end

A lazy string, implemented with Info, but intended specifically for error messages.

module Exn : sig ... end

sexp_of_t uses a global table of sexp converters. To register a converter for a new exception, add [@@deriving_inline sexp][@@@end] to its definition. If no suitable converter is found, the standard converter in Printexc will be used to generate an atomic S-expression.

module Field : sig ... end

OCaml record field.

module Float : sig ... end

Floating-point representation and utilities.

module Floatable : sig ... end
module Fn : sig ... end

various combinators for functions

module Hash : sig ... end
module Hash_intf : sig ... end

Hash_intf.S is the interface which a hash-function must support

module Hash_set : sig ... end
module Hash_set_intf : sig ... end
module Hasher : sig ... end

Signatures required of types which can be used in [@@deriving_inline hash][@@@end].

module Hashtbl : sig ... end
module Hashtbl_intf : sig ... end
module Heap_block : sig ... end

A heap block is a value that is guaranteed to live on the OCaml heap, and is hence guaranteed to be usable with finalization or in a weak pointer. It is an abstract type so we can use the type system to guarantee that the values we put in weak pointers and use with finalizers are heap blocks.

module Identifiable : sig ... end

A signature combining functionality that is commonly used for types that are intended to act as names or identifiers.

module Indexed_container : sig ... end
module Info : sig ... end
module Info_intf : sig ... end

Info is a library for lazily constructing human-readable information as a string or sexp, with a primary use being error messages. Using Info is often preferable to sprintf or manually constructing strings because you don't have to eagerly construct the string --- you only need to pay when you actually want to display the info. which for many applications is rare. Using Info is also better than creating custom exceptions because you have more control over the format.

module Int : sig ... end

OCaml's native integer type.

module Int32 : sig ... end

An int of exactly 32 bits, regardless of the machine.

module Int63 : sig ... end

63-bit integers.

module Int64 : sig ... end
module Int_intf : sig ... end
module Intable : sig ... end
module Invariant : sig ... end
module Lazy : sig ... end

This file is a modified version of lazy.mli from the OCaml distribution.

module List : sig ... end

List operations.

module Map : sig ... end
module Map_intf : sig ... end

See map.mli for comments.

module Maybe_bound : sig ... end
module Monad : sig ... end
module Nativeint : sig ... end
module Option : sig ... end
module Or_error : sig ... end

Type for tracking errors in an Error.t. This is a specialization of the Result type, where the Error constructor carries an Error.t.

module Ordered_collection_common : sig ... end
module Ordering : sig ... end

Ordering is intended to make code that matches on the result of a comparison more concise and easier to read. For example, one would write:

module Poly : sig ... end
module Polymorphic_compare : sig ... end
module Polymorphic_compare_intf : sig ... end

Interfaces used for hiding and replacing polymorphic compare. Including a module with interface S should hide the majority of functions that use polymorphic compare.

module Popcount : sig ... end

This module exposes popcount functions for the various integer types. Functions are exposed in their respective modules.

module Pretty_printer : sig ... end

A list of pretty printers for various types, for use in toplevels.

module Printf : sig ... end
module Linked_queue : sig ... end

This module is a wrapper around OCaml's standard Queue module that follows Base idioms and adds some functions. See Queue_intf for documentation of standard queue functions.

module Queue_intf : sig ... end

An interface for queues that follows Base's conventions, as opposed to OCaml's standard Queue module.

module Random : sig ... end

This is a slightly modified version of the OCaml standard library's random.mli. We want Base's Random module to be different from OCaml's standard one:

module Ref : sig ... end

Module for the type ref

module Result : sig ... end

Result is often used to handle error messages.

module Sequence : sig ... end

A sequence of elements that can be produced one at a time, on demand, normally with no sharing.

module Set : sig ... end
module Set_intf : sig ... end

See set.mli for comments.

module Sexpable : sig ... end

New code should use the @@deriving_inline sexp@@@end syntax directly. These module types (S, S1, S2, and S3) are exported for backwards compatibility only. *

module Sign : sig ... end

A simple type for representing the sign of a numeric value.

module Source_code_position : sig ... end

One typically obtains a Source_code_position.t using a [%here] expression, which is implemented by the ppx_here preprocessor.

module Staged : sig ... end

A type for making staging explicit in the type of a function. For example, you might want to have a function that creates a function for allocating unique identifiers. Rather than using the type:

module String : sig ... end

An extension of the standard StringLabels. If you open Base, you'll get these in the String module.

module Stringable : sig ... end
module String_dict : sig ... end

Efficient static string dictionaries. By static, we mean that new key-value pairs cannot be added after the dictionary is created.

module Sys : sig ... end

Cross-platform system configuration values.

module T : sig ... end
module Type_equal : sig ... end

For representing type equalities otherwise not known by the type-checker.

module Unit : sig ... end

Module for the type unit

module Uchar : sig ... end

Unicode character operations.

module Validate : sig ... end

A module for organizing validations of data structures. Allows standardized ways of checking for conditions, and keeps track of the location of errors by keeping a path to each error found. Thus, if you were validating the following datastructure:

module Variant : sig ... end

OCaml variant type.

module With_return : sig ... end

with_return f allows for something like the return statement in C within f. There are three ways f can terminate:

module Word_size : sig ... end

For determining the word size that the program is using.

module Sexp : sig ... end
module Exported_for_specific_uses : sig ... end
module Export : sig ... end
