Struct frame_metadata::v14::SignedExtensionMetadata

pub struct SignedExtensionMetadata<T: Form = MetaForm> {
    pub identifier: T::String,
    pub ty: T::Type,
    pub additional_signed: T::Type,
}

Metadata of an extrinsic’s signed extension.

Fields

identifier: T::String

ty: T::Type

The type of the signed extension, with the data to be included in the extrinsic.

additional_signed: T::Type

The type of the additional signed data, with the data to be included in the signed payload
