Function capnp::serialize::write_message

pub fn write_message<W, A>(write: W, message: &Builder<A>) -> Result<()>
where
    W: Write,
    A: Allocator,

Writes the provided message to write.

For optimal performance, write should be a buffered writer. flush() will not be called on the writer.

The only source of errors from this function are write.write_all() calls. If you pass in a writer that never returns an error, then this function will never return an error.
