pub const fn new(
    clone: unsafe fn(*const ()) -> RawWaker,
    wake: unsafe fn(*const ()),
    wake_by_ref: unsafe fn(*const ()),
    drop: unsafe fn(*const ()),
) -> RawWakerVTable

Creates a new RawWakerVTable from the provided clone, wake, wake_by_ref, and drop functions.

If the RawWaker will be used to construct a Waker then these functions must all be thread-safe (even though RawWaker is !Send + !Sync). This is because Waker is Send + Sync, and it may be moved to arbitrary threads or invoked by & reference. For example, this means that if the clone and drop functions manage a reference count, they must do so atomically.

However, if the RawWaker will be used to construct a LocalWaker instead, then these functions don’t need to be thread safe. This means that !Send + !Sync data can be stored in the data pointer, and reference counting does not need any atomic synchronization. This is because LocalWaker is not thread safe itself, so it cannot be sent across threads.

clone

This function will be called when the RawWaker gets cloned, e.g. when the Waker/LocalWaker in which the RawWaker is stored gets cloned.

The implementation of this function must retain all resources that are required for this additional instance of a RawWaker and associated task. Calling wake on the resulting RawWaker should result in a wakeup of the same task that would have been awoken by the original RawWaker.

wake

This function will be called when wake is called on the Waker. It must wake up the task associated with this RawWaker.

The implementation of this function must make sure to release any resources that are associated with this instance of a RawWaker and associated task.

wake_by_ref

This function will be called when wake_by_ref is called on the Waker. It must wake up the task associated with this RawWaker.

This function is similar to wake, but must not consume the provided data pointer.

drop

This function will be called when a Waker/LocalWaker gets dropped.

The implementation of this function must make sure to release any resources that are associated with this instance of a RawWaker and associated task.

fn clone(&self) -> RawWakerVTable

Returns a duplicate of the value. Read more

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source. Read more

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter. Read more

fn eq(&self, other: &RawWakerVTable) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more

Performs copy-assignment from self to dest. Read more

fn from(t: T) -> T

Returns the argument unchanged.

fn into(self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

type Owned = T

The resulting type after obtaining ownership.

fn to_owned(&self) -> T

Creates owned data from borrowed data, usually by cloning. Read more

Uses borrowed data to replace owned data, usually by cloning. Read more

type Error = Infallible

The type returned in the event of a conversion error.

fn try_from(value: U) -> Result<T, <T as TryFrom<U>>::Error>

Performs the conversion.

type Error = <U as TryFrom<T>>::Error

The type returned in the event of a conversion error.
