0: u32
Implementations
If the u32 is in a valid format to be a fourcc, get its string form.
Note that this requires the std
feature to be enabled. The [display
] method is an
alternative that does not require this dependency.
If the u32 is in a valid format to be a fourcc, get an opaque type to display it.
This can be treated as a slightly generalized form of [string_form
] that is also
available when the crate does not depend on the standard or alloc
crate.
assert!(UnrecognizedFourcc(828601953).display().is_some());
assert!(UnrecognizedFourcc(0).display().is_none());
