impl<T: Trait + Send + Sync> SignedExtension for CheckMortality<T>[+]

[+] Show hidden undocumented items

type AccountId = T::AccountId

The type which encodes the sender identity.

type Call = T::Call

The type which encodes the call to be dispatched.

type AdditionalSigned = T::Hash

Any additional data that will go into the signed payload. This may be created dynamically from the transaction using the additional_signed function.

type Pre = ()

The type that encodes information that can be passed from pre_dispatch to post-dispatch.

const IDENTIFIER: &'static str[−][−]

Unique identifier of this signed extension.

fn validate(
    &self,
    _who: &Self::AccountId,
    _call: &Self::Call,
    _info: &DispatchInfoOf<Self::Call>,
    _len: usize
) -> TransactionValidity[−]

Validate a signed transaction for the transaction queue.

fn additional_signed(
    &self
) -> Result<Self::AdditionalSigned, TransactionValidityError>[−]

Construct any additional data that should be in the signed payload of the transaction. Can also perform any pre-signature-verification checks and return an error if needed.

fn pre_dispatch(
    self,
    who: &Self::AccountId,
    call: &Self::Call,
    info: &<Self::Call as Dispatchable>::Info,
    len: usize
) -> Result<Self::Pre, TransactionValidityError>[−]

Do any pre-flight stuff for a signed transaction.

fn validate_unsigned(
    _call: &Self::Call,
    _info: &<Self::Call as Dispatchable>::Info,
    _len: usize
) -> Result<ValidTransaction, TransactionValidityError>[−]

Validate an unsigned transaction for the transaction queue.

fn pre_dispatch_unsigned(
    call: &Self::Call,
    info: &<Self::Call as Dispatchable>::Info,
    len: usize
) -> Result<Self::Pre, TransactionValidityError>[−]

Do any pre-flight stuff for a unsigned transaction.

fn post_dispatch(
    _pre: Self::Pre,
    _info: &<Self::Call as Dispatchable>::Info,
    _post_info: &<Self::Call as Dispatchable>::PostInfo,
    _len: usize,
    _result: &Result<(), DispatchError>
) -> Result<(), TransactionValidityError>[−]

Do any post-flight stuff for an extrinsic.

fn identifier() -> Vec<&'static str>[−]

Returns the list of unique identifier for this signed extension.
