Function rmp::encode::write_u32

source ·
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.
