Trait TypeInfo

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

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

Expand description

Implementors return their meta type information.

Required Associated Types§

type Identity: 'static + ?Sized

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.

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.

impl<Address, Call, Signature, Extension> TypeInfo for UncheckedExtrinsic<Address, Call, Signature, Extension>
where Address: StaticTypeInfo, Call: StaticTypeInfo, Signature: StaticTypeInfo, Extension: StaticTypeInfo,

Manual TypeInfo implementation because of custom encoding. The data is a valid encoded Vec<u8>, but requires some logic to extract the signature and payload.

See [UncheckedExtrinsic::encode] and [UncheckedExtrinsic::decode].
