SortArray
SortArrayInt
RESmodule Int = Belt.SortArray.Int
Specalized when key type is int
, more efficient than the generic type
SortArrayString
RESmodule String = Belt.SortArray.String
Specalized when key type is string
, more efficient than the generic type
strictlySortedLengthU
let strictlySortedLengthU: (array<'a>, (. 'a, 'a) => bool) => int
strictlySortedLength
let strictlySortedLength: (array<'a>, ('a, 'a) => bool) => int
strictlySortedLenght(xs, cmp);
return +n
means increasing order -n
means negative order
RESBelt.SortArray.strictlySortedLength([1, 2, 3, 4, 3], (x, y) => x < y) == 4
Belt.SortArray.strictlySortedLength([], (x, y) => x < y) == 0

isSortedU
let isSortedU: (array<'a>, (. 'a, 'a) => int) => bool
isSorted
let isSorted: (array<'a>, ('a, 'a) => int) => bool
isSorted(arr, cmp)
: Returns true if array is increasingly sorted (equal is okay)
stableSortInPlaceByU
let stableSortInPlaceByU: (array<'a>, (. 'a, 'a) => int) => unit
stableSortInPlaceBy
let stableSortInPlaceBy: (array<'a>, ('a, 'a) => int) => unit
stableSortByU
let stableSortByU: (array<'a>, (. 'a, 'a) => int) => array<'a>
stableSortBy
let stableSortBy: (array<'a>, ('a, 'a) => int) => array<'a>
stableSortBy(xs, cmp)
: Returns a fresh array Sort xs
in place using
comparator cmp
, the stable means if the elements are equal, their order will
be preserved

binarySearchBy
let binarySearchBy: (array<'a>, 'a, ('a, 'a) => int) => int
If value is not found and value is less than one or more elements in array, the negative number returned is the bitwise complement of the index of the first element that is larger than value.
If value is not found and value is greater
than all elements in array, the negative number returned is the bitwise
complement of (the index of the last element plus 1)for example, if key
is
smaller than all elements return -1
since lnot(-1) == 0
if key
is larger
than all elements return lnot(-1) == 0
since lnot(- (len + 1)) == len
RESBelt.SortArray.binarySearchBy([1, 2, 3, 4, 33, 35, 36], 33, Pervasives.compare) == 4
