Trait ContainerProvider

pub trait ContainerProvider {
    type Context;
    type Index: Clone + PartialEq + Debug;

    const DEFAULT_CONTAINER: Self::Index;

    // Required methods
    fn get<'a, 'b: 'a>(
        &'b self,
        index: &'a Self::Index,
    ) -> &'b dyn Container<Self::Context>;
    fn get_mut<'a, 'b: 'a>(
        &'b mut self,
        index: &'a Self::Index,
    ) -> &'b mut dyn Container<Self::Context>;
}

A ContainerProvider stores the individual components (Containers) of an application and allows them to be retrieved based on an index.

Note that every possible value for Self::Index must correspond to a valid component. A good choice for an Index is therefore an enum.

Required Associated Constants

const DEFAULT_CONTAINER: Self::Index

The container selected by default (i.e., the start of the application)

Required Associated Types

type Context

Type to be passed as a parameter to Container::input.

type Index: Clone + PartialEq + Debug

Type that enumerates and identifies all containers.

Required Methods

fn get<'a, 'b: 'a>( &'b self, index: &'a Self::Index, ) -> &'b dyn Container<Self::Context>

Get the container identified by the index.

fn get_mut<'a, 'b: 'a>( &'b mut self, index: &'a Self::Index, ) -> &'b mut dyn Container<Self::Context>

Get the container identified by the index (mutable).

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.
