Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
InvalidInput
A function was passed an invalid input.
NotSupported
Something is impossible on the current platform.
Unimplemented
Something is possible, but not yet implemented.
MissingFeature(&'static str)
Piet was compiled without a required feature.
StackUnbalance
A stack pop failed.
BackendError(Box<dyn Error + 'static, Global>)
The backend failed unexpectedly.
MissingFont
A font could not be found.
FontLoadingFailed
Font data could not be loaded.
