namespace bytesimport { bytes } from "https://dotland.deno.dev/x/aleph@v0.2.27/std.ts"; Functionsfbytes.concatConcatenate two binary arrays and return new one. fbytes.containsCheck source array contains pattern array. fbytes.copyBytesCopy bytes from one Uint8Array to another. Bytes from src which don't fit into dst will not be copied. fbytes.equalCheck whether binary arrays are equal to each other. fbytes.findIndexFind first index of binary pattern from a. If not found, then return -1 fbytes.findLastIndexFind last index of binary pattern from a. If not found, then return -1. fbytes.hasPrefixCheck whether binary array starts with prefix. fbytes.hasSuffixCheck whether binary array ends with suffix. fbytes.repeatRepeat bytes. returns a new byte slice consisting of count copies of b.
