val front : sideval back : sideA side appears as a parameter to several operations, such as push and pop, which can operate at either end of a sequence.
val forward : directionval backward : directionA direction appears as a parameter to several operations, such as iter, which can traverse the sequence either forward (from front to back) or backward (from back to front).
The exception Empty is raised by pop and peek operations when applied to an empty sequence.
module Ephemeral : sig ... endThe submodule Ephemeral, also available under the name E, offers an implementation of ephemeral (mutable) sequences.
module Persistent : sig ... endThe submodule Persistent, also available under the name P, offers an implementation of persistent (immutable) sequences.
module P = PersistentP is a short name for the submodule Persistent.
Conversion Functions
The following functions offer fast conversions between ephemeral and persistent sequences.
val snapshot : 'a Ephemeral.t -> 'a Persistent.tsnapshot s constructs and returns a persistent sequence whose elements are the elements of s. It is less efficient than snapshot_and_clear, whose use should be preferred, when possible.
val snapshot_and_clear : 'a Ephemeral.t -> 'a Persistent.tsnapshot_and_clear s constructs and returns a persistent sequence whose elements are the elements of s. As a side effect, it clears s.
val edit : 'a Persistent.t -> 'a Ephemeral.tedit s constructs and returns a new ephemeral sequence whose elements are the elements of s.
Emulation Layers
module Queue : sig ... endThe submodule Queue is a replacement for OCaml's standard Queue module, where a queue is implemented as an ephemeral sequence. Elements are enqueued at the back end of the sequence and dequeued at the front end.
module Stack : sig ... endThe submodule Stack is a replacement for OCaml's standard Stack module, where a stack is implemented as an ephemeral sequence. Elements are pushed and popped at the front end of the sequence.
