Function read_key_from_bytes_with_options 

pub fn read_key_from_bytes_with_options(
    bytes: &[u8],
    options: KeyReadOptions,
) -> Result<Key, KeyBinaryError>

Reads a KEY index from bytes with explicit options.

Errors

KeyBinaryError::InvalidMagic when the signature is not KEY , and KeyBinaryError::InvalidVersion for a version options.input does not accept: CanonicalK1 takes V1 alone, where CompatibilityAurora also takes V1.1.

KeyBinaryError::InvalidHeader when the header is truncated, either table’s size overflows, or a table or a BIF filename runs past the end of bytes. KeyBinaryError::TextDecoding for a BIF filename that is not valid text in the KEY’s encoding.

The BIFs a KEY names are not opened, so a KEY pointing at files that are not on disk reads without complaint. That failure arrives at first lookup instead.
