Unaware

Struct Unaware 

Source
#[repr(transparent)]
pub struct Unaware<T>(pub T);
Expand description

Allows transferring a value that doesn’t implement ThreadAware.

Since the ThreadAware trait is not commonly implemented, this wrapper can be used to allow transferring values that don’t implement ThreadAware.

§Performance Considerations

Care must be taken when using this type - since the value will be moved as is, if it contains shared references to data other threads may use, it can introduce contention, resulting in performance impact.

You should never wrap types that are immediately ThreadAware, hence its name Unaware.

In addition, if the wrapped value contains an Arc with interior mutability somewhere inside, this wrapper should not be used, and an Arc with a PerThread or PerNuma with independent initialization per affinity is a better option.
