MutableMap

Same as Belt.Map, but mutable.

t

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

id

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

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

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

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

cmp

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

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

eq

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.

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

forEach

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

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

reduce

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.

everyU

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

every

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

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

some

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

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

In increasing order.

let getExn: (t<'k, 'a, 'id>, 'k) => 'a

checkInvariantInternal

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

Raise when invariant is not held.

remove

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

remove(m, x) do the in-place modification.

removeMany

let removeMany: (t<'k, 'a, 'id>, array<'k>) => unit

map

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

map(m, f) returns a map with same domain as m, where the associated value a of all bindings of m has been replaced by the result of the application of f to a. The bindings are passed to f in increasing order with respect to the ordering over the type of the keys.
