Trait TypedMetadata 

pub trait TypedMetadata {
    // Required methods
    fn from_meta(meta: Meta) -> Self;
    fn into_meta<Data: 'static>(self) -> Meta;
}

Trait for converting between fat pointer metadata and type-erased Meta.

Implemented for () (for concrete types) and DynMetadata<T> (for trait objects).

Required Methods

fn from_meta(meta: Meta) -> Self

Converts Meta into the corresponding metadata type.

fn into_meta<Data: 'static>(self) -> Meta

Converts metadata type into a type-erased Meta.

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.

Implementations on Foreign Types
