Module String_id.Make_with_validate

Make_with_validate is like Make, but modifies of_string/of_sexp/bin_read_t to raise if validate returns an error. Before using this functor one should be mindful of the performance implications (the validate function will run every time an instance is created) as well as potential versioning issues (when validate changes old binaries still run the old version of the function).

The resulting quickcheck_generator uses a naive Generator.filter to satisfy validate. For complex validation predictes, the generator may spin indefinitely trying to generate a satisfying string. In these cases, the client should shadow quickcheck_generator with a generator that constructs valid strings more directly.

Parameters

Signature

type t = private Core_kernel__.Import.string
val equal : t -> t -> Core_kernel__.Import.bool
val hash_fold_t : Base.Hash.state -> t -> Base.Hash.state
val hash : t -> Base.Hash.hash_value

val bin_write_t : t Bin_prot.Write.writer
val bin_read_t : t Bin_prot.Read.reader
val __bin_read_t__ : (int -> t) Bin_prot.Read.reader

This function only needs implementation if t exposed to be a polymorphic variant. Despite what the type reads, this does *not* produce a function after reading; instead it takes the constructor tag (int) before reading and reads the rest of the variant t afterwards.

val (=) : t -> t -> bool
val (>) : t -> t -> bool
val (<) : t -> t -> bool
val (<>) : t -> t -> bool
val equal : t -> t -> bool
val compare : t -> t -> int

compare t1 t2 returns 0 if t1 is equal to t2, a negative integer if t1 is less than t2, and a positive integer if t1 is greater than t2.

val min : t -> t -> t
val max : t -> t -> t
val ascending : t -> t -> int

ascending is identical to compare. descending x y = ascending y x. These are intended to be mnemonic when used like List.sort ~compare:ascending and List.sort ~cmp:descending, since they cause the list to be sorted in ascending or descending order, respectively.

val descending : t -> t -> int
val between : t -> low:t -> high:t -> bool

between t ~low ~high means low <= t <= high

val clamp_exn : t -> min:t -> max:t -> t

clamp_exn t ~min ~max returns t', the closest value to t such that between t' ~low:min ~high:max is true.

Raises if not (min <= max).
