Structs

ConsumedError

This error indicates that the internal value has been consumed, i.e., its ownership has been moved out.

LockError

This error indicates that the internal value has already been mutably borrowed. At this point, you must wait for other code to release the lock.

You can wrap the desired internal value in this structure to implement a pyclass that can obtain ownership of the internal value.

Traits

MappableDeref

This trait provides compatibility between &T and parking_lot::RwLockReadGuard

MappableDerefMut

This trait provides compatibility between [&mut T] and parking_lot::RwLockWriteGuard

PyWrapperSemverExt

This trait allows you to handle PyWrapperT0 and PyWrapperT1 with the API of PyWrapper<PyWrapperT2>, so you can write future-compatible code.
