string-byte-slice/build/src/buffer.js

Like `string.slice()` but bytewise

import{getByteEnd,getByteStart}from"./bytes.js";


export const bufferSlice=(input,byteStart,byteEnd)=>{

const buffer=globalThis.Buffer.from(input);
const byteStartA=getByteStart(buffer,buffer.length,byteStart);
const byteEndA=getByteEnd(buffer,buffer.length,byteEnd);
return byteStartA===0&&byteEndA>=buffer.length?
buffer.toString():
buffer.toString("utf8",byteStartA,byteEndA)
};
