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.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
