Module computed 

Computed reactive values that derive from other reactive values.

Modules

suspense

Utilities used to track whether asynchronous computeds are currently loading.

Structs

ArcAsyncDerived

A reactive value that is derived by running an asynchronous computation in response to changes in its sources.

ArcMemo

An efficient derived reactive value based on other reactive values.

AsyncDerived

A reactive value that is derived by running an asynchronous computation in response to changes in its sources.

AsyncDerivedFuture

A Future that is ready when an ArcAsyncDerived is finished loading or reloading, and contains its value. .awaiting this clones the value T.

AsyncDerivedReadyFuture

A Future that is ready when an ArcAsyncDerived is finished loading or reloading, but does not contain its value.

AsyncDerivedRefFuture

A Future that is ready when an ArcAsyncDerived is finished loading or reloading, and yields an AsyncDerivedGuard that dereferences to its value.

Memo

A memo is an efficient derived reactive value based on other reactive values.

ScopedFuture

A Future wrapper that sets the Owner and Observer before polling the inner Future.

ScopedFutureUntrackedWithDiagnostics

A Future wrapper that sets the Owner and Observer before polling the inner Future, output of ScopedFuture::new_untracked_with_diagnostics.

Selector

A conditional signal that only notifies subscribers when a change in the source signal’s value changes whether the given function is true.

Functions

create_memoDeprecated

Creates a new memoized, computed reactive value.

create_owning_memoDeprecated

Creates a new memo by passing a function that computes the value.

create_read_slice

Takes a memoized, read-only slice of a signal. This is equivalent to the read-only half of create_slice.

create_selectorDeprecated

A conditional signal that only notifies subscribers when a change in the source signal’s value changes whether the given function is true.

create_selector_with_fnDeprecated

Creates a conditional signal that only notifies subscribers when a change in the source signal’s value changes whether the given function is true.

create_slice

Derives a reactive slice of an RwSignal.

create_write_slice

Creates a setter to access one slice of a signal. This is equivalent to the write-only half of create_slice.

Type Aliases

AsyncDerivedGuard

A read guard that holds access to an async derived resource.
