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

Functions

f
concat(buffers: readonly Uint8Array[]): Uint8Array_

Concatenate an array of byte slices into a single slice.

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

Copy bytes from the source array to the destination array and 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 byte slices are equal to each other.

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

Determines whether the source array contains the needle array.

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 byte slice 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.
