MutableMap

Belt.MutableMap

The top level provides generic mutable map operations.

It also has two specialized inner modules Belt.MutableMap.Int and Belt.MutableMap.String

t

RESCRIPT
type t<'k, 'v, 'id>

id

RESCRIPT
type id<'key, 'id> = Belt_Id.comparable<'key, 'id>

make

RESCRIPT
let make: (~id: id<'k, 'id>) => t<'k, 'a, 'id>

clear

RESCRIPT
let clear: t<'a, 'b, 'c> => unit

isEmpty

RESCRIPT
let isEmpty: t<'a, 'b, 'c> => bool

has

RESCRIPT
let has: (t<'k, 'a, 'b>, 'k) => bool

cmpU

RESCRIPT
let cmpU: (t<'k, 'a, 'id>, t<'k, 'a, 'id>, (. 'a, 'a) => int) => int

cmp

RESCRIPT
let cmp: (t<'k, 'a, 'id>, t<'k, 'a, 'id>, ('a, 'a) => int) => int

cmp(m1, m2, cmp) First compare by size, if size is the same, compare by key, value pair.

eqU

RESCRIPT
let eqU: (t<'k, 'a, 'id>, t<'k, 'a, 'id>, (. 'a, 'a) => bool) => bool

eq

RESCRIPT
let eq: (t<'k, 'a, 'id>, t<'k, 'a, 'id>, ('a, 'a) => bool) => bool

eq(m1, m2, eqf) tests whether the maps m1 and m2 are equal, that is, contain equal keys and associate them with equal data. eqf is the equality predicate used to compare the data associated with the keys.

forEachU

RESCRIPT

forEach

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

forEach(m, f) applies f to all bindings in map m. f receives the 'k as first argument, and the associated value as second argument. The bindings are passed to f in increasing order with respect to the ordering over the type of the keys.

reduceU

RESCRIPT
let reduceU: (t<'k, 'a, 'id>, 'b, (. 'b, 'k, 'a) => 'b) => 'b

reduce

RESCRIPT
let reduce: (t<'k, 'a, 'id>, 'b, ('b, 'k, 'a) => 'b) => 'b

reduce(m, a, f), computes(f(kN, dN) ... (f(k1, d1, a))...), wherek1 ... kNare the keys of all bindings inm(in increasing order), andd1 ... dN` are the associated data.

every

RESCRIPT
let every: (t<'k, 'a, 'id>, ('k, 'a) => bool) => bool

every(m, p) checks if all the bindings of the map satisfy the predicate p.

someU

RESCRIPT
let someU: (t<'k, 'a, 'id>, (. 'k, 'a) => bool) => bool

some

RESCRIPT
let some: (t<'k, 'a, 'id>, ('k, 'a) => bool) => bool

some(m, p) checks if at least one binding of the map satisfy the predicate p.

size

RESCRIPT
let size: t<'k, 'a, 'id> => int

toList

RESCRIPT
let toList: t<'k, 'a, 'id> => list<('k, 'a)>
