pub fn write_pfix<W: RmpWrite>(wr: &mut W, val: u8) -> Result<(), W::Error>Expand description
Encodes and attempts to write an unsigned small integer value as a positive fixint into the given write.
According to the MessagePack specification, a positive fixed integer value is represented using
a single byte in [0x00; 0x7f] range inclusively, prepended with a special marker mask.
The function is strict with the input arguments - it is the user’s responsibility to check if the value fits in the described range, otherwise it will panic.
If you are not sure if the value fits in the given range use write_uint instead, which
automatically selects the most compact integer representation.
§Errors
This function will return FixedValueWriteError on any I/O error occurred while writing the
positive integer marker.
§Panics
Panics if val is greater than 127.
