Function mz_repr::row::read_datum

source ·
unsafe fn read_datum<'a>(data: &'a [u8], offset: &mut usize) -> Datum<'a>
Expand description

Read a datum starting at byte offset.

Updates offset to point to the first byte after the end of the read region.


This function is safe if a Datum was previously written at this offset by push_datum. Otherwise it could return invalid values, which is Undefined Behavior.
