Implementation

pub fn addEntropy(self: *Self, bytes: []const u8) void {
    comptime std.debug.assert(secret_seed_length % rate == 0);
    var i: usize = 0;
    while (i + rate < bytes.len) : (i += rate) {
        self.state.addBytes(bytes[i..][0..rate]);
        self.state.permuteR(8);
    }
    if (i != bytes.len) self.state.addBytes(bytes[i..]);
    self.state.permute();
