Function write_i64

src/encode.rs:461–466

Encodes and attempts to write an `i64` value as a 9-byte sequence into the given write. The first byte becomes the marker and the others will represent the data itself. Note, that this function will encode the given value in 9-byte sequence no matter what, even if the value can be represented using single byte as a fixnum. Also note, that the first byte will always be the i16 marker (`0xd3`). I

/// This function will return `ValueWriteError` on any I/O error occurred while writing either the
/// marker or the data, except the EINTR, which is handled internally.

/// Encodes and attempts to write an `u64` value into the given write using the most efficient
/// representation, returning the marker used.
