Trait scale_info::TypeInfo

pub trait TypeInfo {
    type Identity: ?Sized + 'static;

    // Required method
    fn type_info() -> Type;
}

Implementors return their meta type information.

Required Associated Types

type Identity: ?Sized + 'static

The type identifying for which type info is provided.

Note

This is used to uniquely identify a type via core::any::TypeId::of. In most cases it will just be Self, but can be used to unify different types which have the same encoded representation e.g. reference types Box<T>, &T and &mut T.

Required Methods

fn type_info() -> Type

Returns the static type identifier for Self.

Object Safety

This trait is not object safe.
