Function pushWithStateAssumeCapacity [src]

Standalone function for working with a fixed-size buffer.

Prototype

pub fn pushWithStateAssumeCapacity(buf: []u8, bit_len: *usize, b: u1) void

Parameters

buf: []u8bit_len: *usizeb: u1

Source

  pub fn pushWithStateAssumeCapacity(buf: []u8, bit_len: *usize, b: u1) void {
    const byte_index = bit_len.* >> 3;
    const bit_index = @as(u3, @intCast(bit_len.* & 7));

    buf[byte_index] &= ~(@as(u8, 1) << bit_index);
    buf[byte_index] |= @as(u8, b) << bit_index;

    bit_len.* += 1;
}
