Function rmp::decode::read_u8

pub fn read_u8<R>(rd: &mut R) -> Result<u8, ValueReadError> where R: Read

Attempts to read exactly 2 bytes from the given reader and to decode them as u8 value.

The first byte should be the marker and the second one should represent the data itself.

Errors

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

It also returns ValueReadError::TypeMismatch if the actual type is not equal with the expected one, indicating you with the actual type.
