Method append_u64

merlin/src/transcript.rs:164–166

Convenience method for appending a `u64` to the transcript. The `label` parameter is metadata about the message, and is also appended to the transcript. See the [Transcript Protocols](https://merlin.cool/use/protocol.html) section of the Merlin website for details on labels. # Implementation Calls `append_message` with the 8-byte little-endian encoding of `x`.

(&mut self, label: &'static [u8], x: u64)

    /// Calls `append_message` with the 8-byte little-endian encoding
    /// of `x`.
    pub fn append_u64(&mut self, label: &'static [u8], x: u64) {
        self.append_message(label, &encode_u64(x));
    }

    /// Deprecated.  This function was renamed to
    /// [`append_u64`](Transcript::append_u64).
