Function rmp::encode::write_f64

pub fn write_f64<W: Write>(wr: &mut W, val: f64) -> Result<(), ValueWriteError>

Encodes and attempts to write an f64 value as a 9-byte sequence into the given write.

The first byte becomes the f64 marker and the others will represent the data itself.

Errors

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.
