pub fn write_u32<W: RmpWrite>(
wr: &mut W,
val: u32,
) -> Result<(), ValueWriteError<W::Error>>
Expand description
Encodes and attempts to write an u32
value strictly as a 5-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 5-byte sequence no matter what, even if the value can be represented using single byte as a positive fixnum.
If you need to fit the given buffer efficiently use write_uint
instead, which automatically
selects the appropriate integer representation.
§Errors
This function will return ValueWriteError
on any I/O error occurred while writing either the
marker or the data.
