Struct mpeg4_audio_const::AudioObjectType

source · 
pub struct AudioObjectType(/* private fields */);
Expand description

Represents an audio object type indicator value.

This type can be constructed from a u8,

assert_eq!(AudioObjectType::AAC_LC, AudioObjectType::try_from(2).unwrap());
assert_eq!(2u8, AudioObjectType::AAC_LC.into());

and will accept values that are ‘reserved’ in the spec,

assert_eq!("RESERVED(95)", format!("{:?}", AudioObjectType::try_from(95).unwrap()));

but disallows values that can’t legitimately be represented because they are too large (the maximum representable a-o-t value is 96) and also disallows the ‘escape value’ (value 31 see AOT_ESCAPE_VALUE) which is used as part of the encoding scheme for the a-o-t field rather than as a distinct field value.

assert_eq!(Err(AudioObjectTypeError::EscapeValue), AudioObjectType::try_from(31));
assert_eq!(Err(AudioObjectTypeError::TooLarge(97)), AudioObjectType::try_from(97));
