Expand description

The header of a directory record, because the identifier is variable length (ECMA-119 9.1 fixed fields).

@hadris-spec ECMA-119:9.1 @hadris-compliance partial @hadris-note Fixed fields round-trip, but all identifier, flag, and semantic constraints are not yet validated. @hadris-tests directory::tests::directory_record_parse_roundtrip @hadris-fuzz iso_read

Fields§

§len: u8

The len field.

§extended_attr_record: u8

The extended_attr_record field.

§extent: U32LsbMsb

The LBA of the record

§data_len: U32LsbMsb

The length of the data in bytes

§date_time: DirDateTime

The date_time field.

§flags: u8

The flags field.

§file_unit_size: u8

The file_unit_size field.

§interleave_gap_size: u8

The interleave_gap_size field.

§volume_sequence_number: U16LsbMsb

The volume_sequence_number field.

§file_identifier_len: u8

The file_identifier_len field.
