Trait Extrinsic

pub trait Extrinsic: Sized {
    type Call: TypeInfo;
    type SignaturePayload: SignaturePayload;

    // Provided methods
    fn is_signed(&self) -> Option<bool> { ... }
    fn is_bare(&self) -> bool { ... }
    fn new(
        _call: Self::Call,
        _signed_data: Option<Self::SignaturePayload>,
    ) -> Option<Self> { ... }
}

👎Deprecated: Use ExtrinsicLike along with the CreateTransaction trait family instead

Something that acts like an Extrinsic.

Required Associated Types

type Call: TypeInfo

👎Deprecated: Use ExtrinsicLike along with the CreateTransaction trait family instead

The function call.

type SignaturePayload: SignaturePayload

👎Deprecated: Use ExtrinsicLike along with the CreateTransaction trait family instead

The payload we carry for signed extrinsics.

Usually it will contain a Signature and may include some additional data that are specific to signed extrinsics.

Provided Methods

fn is_signed(&self) -> Option<bool>

👎Deprecated: Use ExtrinsicLike along with the CreateTransaction trait family instead

Is this Extrinsic signed? If no information are available about signed/unsigned, None should be returned.

fn is_bare(&self) -> bool

👎Deprecated: Use ExtrinsicLike along with the CreateTransaction trait family instead

Returns true if this Extrinsic is bare.

fn new( _call: Self::Call, _signed_data: Option<Self::SignaturePayload>, ) -> Option<Self>

👎Deprecated: Use ExtrinsicLike along with the CreateTransaction trait family instead

Create a new old-school extrinsic, either a bare extrinsic if _signed_data is None or a signed transaction is it is Some.

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.
