Trait crux_core::capability::WithContext
source · pub trait WithContext<App, Ef>where
App: App,{
// Required method
fn new_with_context(
context: ProtoContext<Ef, App::Event>
) -> App::Capabilities;
}Expand description
Allows Crux to construct app’s set of required capabilities, providing context they can then use to request effects and dispatch events.
new_with_context is called by Crux and should return an instance of the app’s Capabilities type with
all capabilities constructed with context passed in. Use Context::specialize to
create an appropriate context instance with the effect constructor which should
wrap the requested operations.
Note that this implementation can be generated by the derive macro Effect (in the crux_macros crate).
impl crux_core::WithContext<App, Effect> for Capabilities {
fn new_with_context(
context: crux_core::capability::ProtoContext<Effect, Event>,
) -> Capabilities {
Capabilities {
http: crux_http::Http::new(context.specialize(Effect::Http)),
render: crux_core::render::Render::new(context.specialize(Effect::Render)),
}
}
