Enum SignalReadGuard 

pub enum SignalReadGuard<T, S>
where
    T: 'static,
    S: Storage<T>,
{
    Read(ReadGuard<T, Plain<T>>),
    Memo(ReadGuard<T, Mapped<Plain<Option<<S as Storage<T>>::Wrapped>>, T>>),
    Owned(T),
}

The content of a Signal wrapper read guard, variable depending on the signal type.

Variants

Read(ReadGuard<T, Plain<T>>)

A read signal guard.

Memo(ReadGuard<T, Mapped<Plain<Option<<S as Storage<T>>::Wrapped>>, T>>)

A memo guard.

Owned(T)

A fake guard for derived signals, the content had to actually be cloned, so it’s not a guard but we pretend it is.

Trait Implementations

impl<T, S> Borrow<T> for SignalReadGuard<T, S>

where S: Storage<T>,

fn borrow(&self) -> &T

Immutably borrows from an owned value.

impl<T, S> Clone for SignalReadGuard<T, S>

where S: Storage<T>, T: Clone, Plain<T>: Clone, Mapped<Plain<Option<<S as Storage<T>>::Wrapped>>, T>: Clone,

fn clone(&self) -> SignalReadGuard<T, S>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T, S> Debug for SignalReadGuard<T, S>

where T: 'static + Debug, S: Storage<T> + Debug, <S as Storage<T>>::Wrapped: Debug,

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

Formats the value using the given formatter.

impl<T, S> Deref for SignalReadGuard<T, S>

where S: Storage<T>,

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &<SignalReadGuard<T, S> as Deref>::Target

Dereferences the value.

impl<T, S> Display for SignalReadGuard<T, S>

where S: Storage<T>, T: Display,

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

Formats the value using the given formatter.

impl<T, S> PartialEq<T> for SignalReadGuard<T, S>

where S: Storage<T>, T: PartialEq,

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