Expand description

Helper trait for ComponentInstanceProvider providing strongly-typed access.

Required Methods§

source

fn primary_instance_typed<T: Injectable + ?Sized>( &mut self ) -> Result<ComponentInstancePtr<T>, ComponentInstanceProviderError>

Typesafe version of ComponentInstanceProvider::primary_instance.

source

fn primary_instance_option<T: Injectable + ?Sized>( &mut self ) -> Result<Option<ComponentInstancePtr<T>>, ComponentInstanceProviderError>

Tries to get an instance like TypedComponentInstanceProvider::primary_instance_typed does, but returns None on missing instance.

source

fn instances_typed<T: Injectable + ?Sized>( &mut self ) -> Result<Vec<ComponentInstancePtr<T>>, ComponentInstanceProviderError>

Typesafe version of ComponentInstanceProvider::instances.

source

fn instance_by_name_typed<T: Injectable + ?Sized>( &mut self, name: &str ) -> Result<ComponentInstancePtr<T>, ComponentInstanceProviderError>

Typesafe version of ComponentInstanceProvider::instance_by_name.

source

fn instance_by_name_option<T: Injectable + ?Sized>( &mut self, name: &str ) -> Result<Option<ComponentInstancePtr<T>>, ComponentInstanceProviderError>

Tries to get an instance like TypedComponentInstanceProvider::instance_by_name_typed does, but returns None on missing instance.
