bit-encode

Low level bit encoder for buffers

npm install bit-encode

Usage

var bits = require('bit-encode')

var buf = Buffer([0])

console.log(bits.get(buf, 0)) // get first bit, returns false (0)

bits.set(buf, 0, true) // set first bit

console.log(bits.get(buf, 0)) // get first bit, returns true (1)

API

var bool = bits.get(buffer, index)

Read the bit at index. A byte in the buffer contains 8 bits so index 0 would return the first bit in the first byte and index 8 would return the first bit in the second byte.

var updated = bits.set(buffer, index, bool)

Set the bit at index. Returns true if a bit was updated false otherwise.
