Implementations

impl<T: Config> CheckNonce<T>

pub fn from(nonce: T::Nonce) -> Self

utility constructor. Used only in client/factory code.

Trait Implementations

impl<T: Clone + Config> Clone for CheckNonce<T>

where T::Nonce: Clone,

fn clone(&self) -> CheckNonce<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Config> Debug for CheckNonce<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: Config> Decode for CheckNonce<T>

where T::Nonce: HasCompact,

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy, ) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self>, ) -> Result<DecodeFinished, Error>

where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>

where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl<T: Config> Encode for CheckNonce<T>

where T::Nonce: HasCompact,

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy, )

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8>

Convert self to an owned vector.

fn using_encoded<__CodecOutputReturn, __CodecUsingEncodedCallback: FnOnce(&[u8]) -> __CodecOutputReturn>( &self, f: __CodecUsingEncodedCallback, ) -> __CodecOutputReturn

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl<T: PartialEq + Config> PartialEq for CheckNonce<T>

where T::Nonce: PartialEq,

fn eq(&self, other: &CheckNonce<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T: Config> SignedExtension for CheckNonce<T>

where T::RuntimeCall: Dispatchable<Info = DispatchInfo>,

const IDENTIFIER: &'static str = "CheckNonce"

Unique identifier of this signed extension.

type AccountId = <T as Config>::AccountId

The type which encodes the sender identity.

type Call = <T as Config>::RuntimeCall

The type which encodes the call to be dispatched.

type AdditionalSigned = ()

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.

fn additional_signed(&self) -> Result<(), 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 validate( &self, who: &Self::AccountId, _call: &Self::Call, _info: &DispatchInfoOf<Self::Call>, _len: usize, ) -> TransactionValidity

Validate a signed transaction for the transaction queue.

fn pre_dispatch( self, who: &Self::AccountId, _call: &Self::Call, _info: &DispatchInfoOf<Self::Call>, _len: usize, ) -> Result<(), 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<(), TransactionValidityError>

Do any pre-flight stuff for a unsigned transaction.

fn post_dispatch( _pre: Option<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 metadata() -> Vec<SignedExtensionMetadata>

Returns the metadata for this signed extension.

impl<T> TypeInfo for CheckNonce<T>

where T::Nonce: HasCompact, T: Config + 'static,

type Identity = CheckNonce<T>

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
