Function read_fixext4

Source
pub fn read_fixext4<R: RmpRead>(
    rd: &mut R,
) -> Result<(i8, [u8; 4]), ValueReadError<R::Error>>
Expand description

Attempts to read exactly 6 bytes from the given reader and interpret them as a fixext4 type with data attached.

According to the MessagePack specification, a fixext4 stores an integer and a byte array whose length is 4 bytes. Its marker byte is 0xd6.

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

ยงErrors

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