Implementation

pub fn fill(self: *Self, buf: []u8) void {
    var i: usize = 0;
    while (true) {
        const left = buf.len - i;
        const n = @min(left, rate);
        self.state.extractBytes(buf[i..][0..n]);
        if (left == 0) break;
        self.state.permuteR(8);
        i += n;
    }
    self.state.permuteRatchet(6, rate);
}
