Struct dioxus_signals::Write

pub struct Write<'a, T: ?Sized + 'static, S: AnyStorage = UnsyncStorage> { /* private fields */ }

A mutable reference to a signal’s value.

T is the current type of the write S is the storage type of the signal

Implementations

impl<'a, T: ?Sized + 'static, S: AnyStorage> Write<'a, T, S>

pub fn map<O: ?Sized>( myself: Self, f: impl FnOnce(&mut T) -> &mut O ) -> Write<'a, O, S>

Map the mutable reference to the signal’s value to a new type.

pub fn filter_map<O: ?Sized>( myself: Self, f: impl FnOnce(&mut T) -> Option<&mut O> ) -> Option<Write<'a, O, S>>

Try to map the mutable reference to the signal’s value to a new type

pub fn downcast_lifetime<'b>(mut_: Self) -> Write<'b, T, S>

where 'a: 'b,

Downcast the lifetime of the mutable reference to the signal’s value.

This function enforces the variance of the lifetime parameter 'a in Mut. Rust will typically infer this cast with a concrete type, but it cannot with a generic type.

Trait Implementations

impl<T: ?Sized + 'static, S: AnyStorage> Deref for Write<'_, T, S>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<T: ?Sized, S: AnyStorage> DerefMut for Write<'_, T, S>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.
