Helper trait for ComponentInstanceProvider providing strongly-typed access.

Required Methods

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

Typesafe version of ComponentInstanceProvider::primary_instance.

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.

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

Typesafe version of ComponentInstanceProvider::instances.

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

Typesafe version of ComponentInstanceProvider::instance_by_name.

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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
