Key collection for CtxMap.

Use schema macro to define a type that implement Schema.

Required Methods

fn data() -> &'static SchemaData

Provided Methods

fn key<T: ?Sized>() -> Key<Self, T>

fn key_mut<T: ?Sized>() -> KeyMut<Self, T>

fn key_with_default<Init, ToRef, V, T>( init: Init, to_ref: ToRef, ) -> Key<Self, T>

where Init: Send + Sync + Fn() -> V + 'static, ToRef: Send + Sync + Fn(&V) -> &T + 'static, V: 'static, T: ?Sized,

fn key_mut_with_default<Init, ToRef, ToMut, V, T>( init: Init, to_ref: ToRef, to_mut: ToMut, ) -> KeyMut<Self, T>

where Init: Send + Sync + Fn() -> V + 'static, ToRef: Send + Sync + Fn(&V) -> &T + 'static, ToMut: Send + Sync + Fn(&mut V) -> &mut T + 'static, V: 'static, T: ?Sized,

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.
