Struct frame_system::CheckMortality
source · pub struct CheckMortality<T: Config + Send + Sync>(pub Era, _);
Expand description
Check for transaction mortality.
The extension adds [Era
] to every signed extrinsic. It also contributes to the signed data, by
including the hash of the block at [Era::birth
].
§Transaction Validity
The extension affects longevity
of the transaction according to the [Era
] definition.

§type Implicit = <T as Config>::Hash
type Implicit = <T as Config>::Hash
Any additional data which was known at the time of transaction construction and can be
useful in authenticating the transaction. This is determined dynamically in part from the
on-chain environment using the
implicit
function and not directly contained in the
transaction itself and therefore is considered “implicit”.source§fn implicit(&self) -> Result<Self::Implicit, TransactionValidityError>
fn implicit(&self) -> Result<Self::Implicit, TransactionValidityError>
Determine any additional data which was known at the time of transaction construction and
can be useful in authenticating the transaction. The expected usage of this is to include in
any data which is signed and verified as part of transaction validation. Also perform any
pre-signature-verification checks and return an error if needed.

but instead of executing the call, execute
substitute
instead. Since this doesn’t actually
dispatch the call, it doesn’t need to consume it and so call
can be passed as a reference.source§impl<Q, K> Equivalent<K> for Q
