Extensions

We add extensions for Int and Float arrays to make them bin-able, comparable, sexpable, and blit-able (via Blit.S). Permissioned provides fine-grained access control for arrays.

Operations supporting "normalized" indexes are also available.

module Int : sig ... end

module Float : sig ... end

val normalize : 'a t -> Core_kernel__.Import.int -> Core_kernel__.Import.int: normalize array index returns a new index into the array such that if the index is less than zero, the returned index will "wrap around" -- i.e., array.(normalize array (-1)) returns the last element of the array.

val slice : 'a t -> Core_kernel__.Import.int -> Core_kernel__.Import.int -> 'a t: slice t start stop returns a new array including elements t.(start) through t.(stop-1), normalized Python-style with the exception that stop = 0 is treated as stop = length t.

val nget : 'a t -> Core_kernel__.Import.int -> 'a: Array access with normalized index.

val nset : 'a t -> Core_kernel__.Import.int -> 'a -> Core_kernel__.Import.unit: Array modification with normalized index.

module Permissioned : sig ... end: The Permissioned module gives the ability to restrict permissions on an array, so you can give a function read-only access to an array, create an immutable array, etc.
