Expand description

Something that acts like an Extrinsic.

Required Associated Types§

type Call

The function call.

type SignaturePayload

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>

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

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

Create new instance of the extrinsic.

Extrinsics can be split into:

Inherents (no signature; created by validators during block production)
Unsigned Transactions (no signature; represent “system calls” or other special kinds of calls) 3. Signed Transactions (with signature; a regular transactions with known origin)
