Utilities to manipulate Uint8Arrays that are not built-in to JavaScript

Classes

c
BytesList()

An abstraction of multiple Uint8Arrays

  • add(
    value: Uint8Array,
    start?: number,
    end?
    ): void

    Push bytes with given offset infos

  • concat(): Uint8Array

    Concatenate chunks into single Uint8Array copied.

  • get(i: number): number

    Get indexed byte from chunks

  • getChunkIndex(pos: number): number

    Find chunk index in which pos locates by binary-search returns -1 if out of range

  • iterator(start?: number): IterableIterator<number>

    Iterator of bytes from given position

  • shift(n: number): void

    Drop head n bytes.

  • size()

    Total size of bytes

  • slice(
    start: number,
    end?: number
    ): Uint8Array

    Returns subset of bytes copied

Functions

f
concat(...buf: Uint8Array[]): Uint8Array

Concatenate the given arrays into a new Uint8Array.

f
copy(
src: Uint8Array,
dst: Uint8Array,
off?: number
): number

Copy bytes from the src array to the dst array. Returns the number of bytes copied.

f
endsWith(
source: Uint8Array,
suffix: Uint8Array
): boolean

Returns true if the suffix array appears at the end of the source array, false otherwise.

f
equals(
a: Uint8Array,
b: Uint8Array
): boolean

Check whether binary arrays are equal to each other.

f
includesNeedle(
source: Uint8Array,
needle: Uint8Array,
start?: number
): boolean

Returns true if the source array contains the needle array, false otherwise.

f
indexOfNeedle(
source: Uint8Array,
needle: Uint8Array,
start?: number
): number

Returns the index of the first occurrence of the needle array in the source array, or -1 if it is not present.

f
lastIndexOfNeedle(
source: Uint8Array,
needle: Uint8Array,
start?: number
): number

Returns the index of the last occurrence of the needle array in the source array, or -1 if it is not present.

f
repeat(
source: Uint8Array,
count: number
): Uint8Array

Returns a new Uint8Array composed of count repetitions of the source array.

f
startsWith(
source: Uint8Array,
prefix: Uint8Array
): boolean

Returns true if the prefix array appears at the start of the source array, false otherwise.
