Struct Completion 

pub struct Completion;

Just an empty type, but it’s never equal to itself.

Vc<Completion> can be used as return value instead of () to have a concrete reference that can be awaited. It will invalidate the awaiting task everytime the referenced task has been executed.

Note: PartialEq is not implemented since it doesn’t make sense to compare Completion this way. You probably want to use ReadRef::ptr_eq instead.

Implementations

impl Completion

pub fn immutable() -> Vc<Self>

This will always be the same and never invalidates the reading task.

impl Completion

pub fn new() -> Vc<Self>

This will always be a new completion and invalidates the reading task.
