Module prelude

Reexports frequently-used traits.

Traits

• DefinedAt
  Describes where the signal was defined. This is used for diagnostic warnings and is purely a debug-mode tool.
• Dispose
  Allows disposing an arena-allocated signal before its owner has been disposed.
• FlattenOptionRefOption
  Helper trait to implement flatten() on Option<&Option<T>>.
• FromLocal
  Converts some value into a locally-stored type, using LocalStorage.
• FromStream
  Allows creating a signal from an async Stream.
• Get
  Clones the value of the signal, without tracking the value reactively. and subscribes the active reactive observer (an effect or computed) to changes in its value.
• GetUntracked
  Clones the value of the signal, without tracking the value reactively.
• GetValue
  A variation of the Get trait that provides a signposted “always-non-reactive” API. E.g. for StoredValue.
• IsDisposed
  Checks whether a signal has already been disposed.
• Notify
  Notifies subscribers of a change in this signal.
• Read
  Give read-only access to a signal’s value by reference through a guard type, and subscribes the active reactive observer (an effect or computed) to changes in its value.
• ReadOptional
  An alternative Read trait that works with Option<Readable> types.
• ReadUntracked
  Give read-only access to a signal’s value by reference through a guard type, without tracking the value reactively.
• ReadUntrackedOptional
  An alternative ReadUntracked trait that works with Option<Readable> types.
• ReadValue
  A variation of the Read trait that provides a signposted “always-non-reactive” API. E.g. for StoredValue.
• Set
  Updates the value of the signal by replacing it.
• SetValue
  A variation of the Set trait that provides a signposted “always-non-reactive” API. E.g. for StoredValue.
• ToStream
  Allows converting a signal into an async Stream.
• Track
  Allows tracking the value of some reactive data.
• UntrackableGuard
  A reactive, mutable guard that can be untracked to prevent it from notifying subscribers when it is dropped.
• Update
  Updates the value of a signal by applying a function that updates it in place, notifying its subscribers that the value has changed.
• UpdateUntracked
  Updates the value of a signal by applying a function that updates it in place, without notifying subscribers.
• UpdateValue
  A variation of the Update trait that provides a signposted “always-non-reactive” API. E.g. for StoredValue.
• With
  Give read-only access to a signal’s value by reference inside a closure, and subscribes the active reactive observer (an effect or computed) to changes in its value.
• WithOptional
  An alternative With trait that works with Option<Withable> types.
• WithUntracked
  Give read-only access to a signal’s value by reference inside a closure, without tracking the value reactively.
• WithUntrackedOptional
  An alternative WithUntracked trait that works with Option<Withable> types.
• WithValue
  A variation of the With trait that provides a signposted “always-non-reactive” API. E.g. for StoredValue.
• Write
  Gives mutable access to a signal’s value through a guard type. When the guard is dropped, the signal’s subscribers will be notified.
• WriteValue
  A variation of the Write trait that provides a signposted “always-non-reactive” API. E.g. for StoredValue.
