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.
QualityTooLow
set_quality()
was used with a minimum quality, and the minimum could not be achieved
ValueOutOfRange
Function called with invalid arguments
OutOfMemory
Either the system/process really hit a limit, or some data like image size was ridiculously wrong. Could be a bug too
Aborted
Progress callback said to stop
InternalError
Some terrible inconsistency happened
BufferTooSmall
Slice needs to be bigger, or width/height needs to be smaller
InvalidPointer
NULL pointer or use-after-free in the C API
Unsupported
Congratulations, you’ve discovered an edge case
