Function rmp::decode::read_fixext2

pub fn read_fixext2<R>(rd: &mut R) -> Result<(i8, [u8; 2]), ValueReadError> where R: Read

Attempts to read exactly 4 bytes from the given reader and interpret them as a fixext2 type with data attached.

According to the MessagePack specification, a fixext2 stores an integer and a byte array whose length is 2 bytes. Its marker byte is 0xd5.

Note, that this function copies a byte array from the reader to the output buffer, which is unlikely if you want zero-copy functionality.

Errors

This function will return ValueReadError on any I/O error while reading either the marker or the data.
