+//! This module implements a Stack, which is useful for implementing a parser
+//! with variable lookahead, as it would allow to pop elements which are below
+//! the top-element, and maintain a top counter which would be in charge of
+//! moving these elements once shifted.
+use std::ptr;
+
+/// This container implements a stack and a queue in a single vector:
+/// - stack: buf[..top]
+/// - queue: buf[top + gap..]
+///
+/// This structure is meant to avoid moving data when the head of the queue is
+/// transfered to the top of the stack. Also, sometimes we need to set items
+/// aside from the top of a stack, and then push them back onto the stack later.
+/// The queue is for storing these set-aside values. Since they live in the same
+/// buffer as the stack, values can be "set aside" and "pushed back on" without
+/// moving them at all.
+///
+/// In the context of an LR parser, the stack contains shifted elements, and the
+/// queue contains the lookahead. If the lexer is completely independent of the
+/// parser, all tokens could be queued before starting the parser.
+///
+/// The following statements describe how this structure is meant to be used and
+/// is described as a stack and a queue displayed as follow:
+/// [...stack...] <gap> [...queue...]
+///
+/// New elements are always inserted in the queue with `enqueue`:
+/// [a, b] <no gap> []
+/// * enqueue(c)
+/// [a, b] <no gap> [c]
+///
+/// These elements are then moved to the stack with `shift`:
+/// [a, b] <no gap> [c]
+/// * shift()
+/// [a, b, c] <no gap> []
+///
+/// The stack top can be set aside in the queue with `unshift`:
+/// [a, b, c] <no gap> []
+/// * unshift()
+/// [a, b] <no gap> [c]
+///
+/// The stack top can be removed with `pop`:
+/// [a, b] <no gap> [c]
+/// * pop() -> b
+/// [a] <gap: 1> [c]
+/// * pop() -> a
+/// [] <gap: 2> [c]
+///
+/// New elements can be added to the front of the queue with `push_next`, which
+/// also moves the content of the queue to ensure that `shift` can be used
+/// afterward:
+/// [] <gap: 2> [c]
+/// * push_next(d)
+/// [] <no gap> [d, c]
+///
+/// These operations are used by LR parser, to add lookahead with `enqueue`, to
+/// shift tokens with `shift`, to save tokens to be replayed with `unshift`, to
+/// reduce a set of tokens and replace it by a non-terminal with `pop` and
+/// `push_next`.
