Crate relm_state [−] [src]

This crate provide the non-GUI part of relm: Basic component and message connection methods.

Macros

connect	Connect events to sending a message.
connect_async	Connect an asynchronous method call to send a message. The variants with `$fail_msg` will send this message when there's an error. Those without this argument will ignore the error.
connect_async_full	Like `connect_async!`, but also return a `Cancellable` to control the asynchronous request.
connect_async_func	Connect an asynchronous function call to send a message. The variants with `$fail_msg` will send this message when there's an error. Those without this argument will ignore the error.
connect_async_func_full	Like `connect_async_func!`, but also return a `Cancellable` to control the asynchronous request.
connect_stream	Connect events to sending a message. Similar to `connect!` but wants a stream instead of a component.

EventStream	A stream of messages to be used for widget/signal communication and inter-widget communication.
Relm	Handle event stream to send messages to the `update()` method.

DisplayVariant	Format trait for enum variants.
Update	Trait for a basic (non-widget) component. A component has a model (data) associated with it and can mutate it when it receives a message (in the `update()` method).
UpdateNew	Trait for an `Update` object that can be created directly. This is useful for non-widget component.

execute	Create a bare component, i.e. a component only implementing the Update trait, not the Widget trait.
init_component	Initialize a component by creating its subscriptions and dispatching the messages from the stream.
