Function regex_automata::util::wire::write_endianness_check

pub(crate) fn write_endianness_check<E: Endian>(
    dst: &mut [u8],
) -> Result<usize, SerializeError>

Writes 0xFEFF as an integer using the given endianness.

This is useful for writing into the header of a serialized object. It can be read during deserialization as a sanity check to ensure the proper endianness is used.

Upon success, the total number of bytes written is returned.
