Expand description

Object Type Identification values.

§Conversions to and from u8

Conversion to or from u8 will work for any value.

assert_eq!(ObjectTypeIdentifier::VISUAL_ISO_IEC_13818_2_MAIN_PROFILE, 0x61.into());
assert_eq!(0x61u8, ObjectTypeIdentifier::VISUAL_ISO_IEC_13818_2_MAIN_PROFILE.into());

§Debug implementation

The implementation of Debug tries to be helpful,

assert_eq!(
    "VISUAL_ISO_IEC_13818_2_MAIN_PROFILE(0x61)",
    format!("{:?}", ObjectTypeIdentifier::VISUAL_ISO_IEC_13818_2_MAIN_PROFILE)
);

§Identifier values without provided constants

Constants are not provided for the range of values that the spec notes are reserved, but you are still able to create ObjectTypeIdentification instances taking these values for the sake of forward compatibility.

The spec also notes that some identifier values have been withdrawn and are deprecated. Constants are not provided for these either.

Finally, some values are marked for user private use, meaning that future versions of the spec will avoid using these values.

While there are no specific constants for any of these, the implementation of Debug still gives them special treatment,

assert_eq!("RESERVED(0x0b)", format!("{:?}", ObjectTypeIdentifier::from(0x0b)));
assert_eq!("WITHDRAWN(0xa5)", format!("{:?}", ObjectTypeIdentifier::from(0xa5)));
assert_eq!("USER_PRIVATE(0xc0)", format!("{:?}", ObjectTypeIdentifier::from(0xc0)))

§Defining constants

You may define your own constant values. For example for application specific values that the spec puts in the user private range. Note however that you can’t change the output which the Debug implementation produces for these values.

const MY_SPECIAL_OBJECT_TYPE: ObjectTypeIdentifier = ObjectTypeIdentifier(0xc1);
match other_oti {
    MY_SPECIAL_OBJECT_TYPE => println!("special object"),
    _ => println!("other type"),
}
// can't customise this "USER_PRIVATE" text,
assert_eq!("USER_PRIVATE(0xc1)", format!("{:?}", MY_SPECIAL_OBJECT_TYPE))
