Struct OccupiedStateMapEntry

Source

pub struct OccupiedStateMapEntry<'a, T>where
    T: StateValue,
{ /* private fields */ }

Expand description

A view into an occupied entry in a state map.

This struct is part of StateMapEntry.

Implementations§

Source §

impl<'a, T> OccupiedStateMapEntry<'a, T>
where T: StateValue,

Source

pub fn get(&self) -> &T

Gets a reference to the value in the entry.

Source

pub fn get_mut(&mut self) -> &mut T

Gets a mutable reference to the value in the entry.

See also into_mut to get a reference tied to the lifetime of the map directly.

Source

pub fn into_mut(self) -> &'a mut T

Converts the entry into a mutable reference to the value in the entry with a lifetime bound to the map itself.

Source

pub fn insert(&mut self, value: T) -> T

Sets the value of the entry, and returns the entry’s old value.

Source

pub fn remove(self) -> T

Takes the value out of the entry, and returns it.

Trait Implementations§

impl<T> Debug for OccupiedStateMapEntry<'_, T>
where T: StateValue + Debug,

Source §

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

Formats the value using the given formatter. Read more

Source §

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

Source §

impl<T> Borrow<T> for T
where T: ?Sized,

Source §

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

Source §

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

Mutably borrows from an owned value. Read more

§

impl<T> Downcast for T
where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

§

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

impl<T> DowncastSync for T
where T: Any + Send + Sync,

§

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.

Source §

impl<T> From<T> for T

Source §

fn from(t: T) -> T

Returns the argument unchanged.

Source §

impl<T> FsChangeNote for T
where T: Debug + Any + Send + Sync,

Source §

fn as_any(&self) -> &(dyn Any + 'static)

Access any.

Source §

impl<T> IntoEither for T

Source §

fn into_either(self, into_left: bool) -> Either<Self, Self>

Converts self into a Left variant of Either<Self, Self> if into_left is true. Converts self into a Right variant of Either<Self, Self> otherwise. Read more
