Struct PrepareContext

Source

pub struct PrepareContext<'a, T: RuntimeFactors, F: Factor> { /* private fields */ }

Expand description

A PrepareContext is passed to Factor::prepare.

This gives the factor access to app state and the app component.

Implementations§

Source §

impl<'a, T: RuntimeFactors, F: Factor> PrepareContext<'a, T, F>

Source

pub fn app_state(&self) -> &'a F::AppState

Get the app state related to the factor.

Source

pub fn app_component(&self) -> &'a AppComponent<'_>

Get the app component.

Source

pub fn instance_builder<U: Factor>(&mut self) -> Result<&mut U::InstanceBuilder>

Returns the prepared FactorInstanceBuilder for the given Factor.

Fails if the current RuntimeFactors does not include the given Factor or if the given Factor’s builder has not been prepared yet (because it is sequenced after this factor).
