Phoenix.LiveView.AsyncResult (Phoenix LiveView v1.0.10)
View SourceProvides a data structure for tracking the state of an async assign.
See the Async Operations section of the Phoenix.LiveView docs for more information.
Fields
:ok?- When true, indicates the:resulthas been set successfully at least once.:loading- The current loading state:failed- The current failed state:result- The successful result of the async task
Summary
Functions
Updates the failed state.
Creates an async result in loading state.
Updates the loading state.
Updates the loading state of an existing async_result.
Creates a successful result.
Updates the successful result.
Functions
Updates the failed state.
When failed, the loading state will be reset to nil.
If the result was previously ok?, both result and
failed will be set.
Examples
iex> result = AsyncResult.loading()
iex> result = AsyncResult.failed(result, {:exit, :boom})
iex> result.failed
{:exit, :boom}
iex> result.loading
nilCreates an async result in loading state.
Examples
iex> result = AsyncResult.loading()
iex> result.loading
true
iex> result.ok?
falseUpdates the loading state.
When loading, the failed state will be reset to nil.
Examples
iex> result = AsyncResult.loading(%{my: :loading_state})
iex> result.loading
%{my: :loading_state}
iex> result = AsyncResult.loading(result)
iex> result.loading
trueUpdates the loading state of an existing async_result.
When loading, the failed state will be reset to nil.
If the result was previously ok?, both result and
loading will be set.
Examples
iex> result = AsyncResult.loading()
iex> result = AsyncResult.loading(result, %{my: :other_state})
iex> result.loading
%{my: :other_state}Creates a successful result.
The :ok? field will also be set to true to indicate this result has
completed successfully at least once, regardless of future state changes.
Examples
iex> result = AsyncResult.ok("initial result")
iex> result.ok?
true
iex> result.result
"initial result"Updates the successful result.
The :ok? field will also be set to true to indicate this result has
completed successfully at least once, regardless of future state changes.
When ok'd, the loading and failed state will be reset to nil.
Examples
iex> result = AsyncResult.loading()
iex> result = AsyncResult.ok(result, "completed")
iex> result.ok?
true
iex> result.result
"completed"
iex> result.loading
nil
