Struct AnyKey

pub struct AnyKey(/* private fields */);

Type-erased key for the Registry.

Implementations

impl AnyKey

pub fn as_any(&self) -> &dyn Any

Cast the key to dyn Any.

pub fn is<K: Any>(&self) -> bool

Returns whether the key is of type K.

Equivalent to self.as_any().is::<K>().

pub fn is_anonymous(&self) -> bool

Returns whether the key corresponds to an anonymous await-tree.

pub fn downcast_ref<K: Any>(&self) -> Option<&K>

Returns the key as a reference to type K, if it is of type K.

Equivalent to self.as_any().downcast_ref::<K>().

Trait Implementations

impl Clone for AnyKey

fn clone(&self) -> AnyKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AnyKey

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

Formats the value using the given formatter.

impl Display for AnyKey

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

Formats the value using the given formatter.

impl Hash for AnyKey

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for AnyKey

fn eq(&self, other: &Self) -> 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.
