MutableStack

First in last out stack. This module implements stacks, with in-place modification.

t

RESCRIPT

type t<'a>

make

RESCRIPT

let make: unit => t<'a>

Returns a new stack, initially empty.

clear

RESCRIPT

let clear: t<'a> => unit

Discard all elements from the stack.

copy

RESCRIPT

let copy: t<'a> => t<'a>

copy(x) O(1) operation, return a new stack.

push

RESCRIPT

let push: (t<'a>, 'a) => unit

popUndefined

RESCRIPT

let popUndefined: t<'a> => Js.undefined<'a>

pop

RESCRIPT

let pop: t<'a> => option<'a>

topUndefined

RESCRIPT

let topUndefined: t<'a> => Js.undefined<'a>

top

RESCRIPT

let top: t<'a> => option<'a>

isEmpty

RESCRIPT

let isEmpty: t<'a> => bool

size

RESCRIPT

let size: t<'a> => int

forEachU

RESCRIPT

let forEachU: (t<'a>, 'a => unit) => unit

forEach

RESCRIPT

let forEach: (t<'a>, 'a => unit) => unit

dynamicPopIterU

RESCRIPT

let dynamicPopIterU: (t<'a>, 'a => unit) => unit

dynamicPopIter

RESCRIPT

let dynamicPopIter: (t<'a>, 'a => unit) => unit

dynamicPopIter(s, f) apply f to each element of s. The item is poped before applying f, s will be empty after this opeartion. This function is useful for worklist algorithm.
