Trait Implementations

impl<T: Clone, S: Clone> Clone for SkipCheckIfFeeless<T, S>

fn clone(&self) -> SkipCheckIfFeeless<T, S>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T, S: Encode> Debug for SkipCheckIfFeeless<T, S>

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

Formats the value using the given formatter.

impl<T, S> Decode for SkipCheckIfFeeless<T, S>

where S: Decode, PhantomData<T>: Decode,

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, S> Encode for SkipCheckIfFeeless<T, S>

where S: Encode, PhantomData<T>: Encode,

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<R, F>(&self, f: F) -> R

where F: FnOnce(&[u8]) -> R,

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

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl<T, S> From<S> for SkipCheckIfFeeless<T, S>

fn from(s: S) -> Self

Converts to this type from the input type.

impl<T: PartialEq, S: PartialEq> PartialEq for SkipCheckIfFeeless<T, S>

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl<T: Config + Send + Sync, S: TransactionExtension<T::RuntimeCall>> TransactionExtension<<T as Config>::RuntimeCall> for SkipCheckIfFeeless<T, S>

where T::RuntimeCall: CheckIfFeeless<Origin = OriginFor<T>>,

const IDENTIFIER: &'static str = S::IDENTIFIER

Unique identifier of this signed extension.

type Implicit = <S as TransactionExtension<<T as Config>::RuntimeCall>>::Implicit

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”.

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.

type Val = Intermediate<<S as TransactionExtension<<T as Config>::RuntimeCall>>::Val, <<<T as Config>::RuntimeCall as Dispatchable>::RuntimeOrigin as OriginTrait>::PalletsOrigin>

The type that encodes information that can be passed from validate to prepare.

type Pre = Intermediate<<S as TransactionExtension<<T as Config>::RuntimeCall>>::Pre, <<<T as Config>::RuntimeCall as Dispatchable>::RuntimeOrigin as OriginTrait>::PalletsOrigin>

The type that encodes information that can be passed from prepare to post_dispatch.

fn weight(&self, call: &T::RuntimeCall) -> Weight

The weight consumed by executing this extension instance fully during transaction dispatch.

fn validate( &self, origin: DispatchOriginOf<T::RuntimeCall>, call: &T::RuntimeCall, info: &DispatchInfoOf<T::RuntimeCall>, len: usize, self_implicit: S::Implicit, inherited_implication: &impl Encode, source: TransactionSource, ) -> ValidateResult<Self::Val, T::RuntimeCall>

Validate a transaction for the transaction queue.

fn prepare( self, val: Self::Val, origin: &DispatchOriginOf<T::RuntimeCall>, call: &T::RuntimeCall, info: &DispatchInfoOf<T::RuntimeCall>, len: usize, ) -> Result<Self::Pre, TransactionValidityError>

Do any pre-flight stuff for a transaction after validation.

fn post_dispatch_details( pre: Self::Pre, info: &DispatchInfoOf<T::RuntimeCall>, post_info: &PostDispatchInfoOf<T::RuntimeCall>, len: usize, result: &DispatchResult, ) -> Result<Weight, TransactionValidityError>

Do any post-flight stuff for an extrinsic.

fn metadata() -> Vec<TransactionExtensionMetadata>

Returns the metadata for this extension.

fn post_dispatch( pre: Self::Pre, info: &<Call as Dispatchable>::Info, post_info: &mut <Call as Dispatchable>::PostInfo, len: usize, result: &Result<(), DispatchError>, ) -> Result<(), TransactionValidityError>

A wrapper for post_dispatch_details that refunds the unspent weight consumed by this extension into the post dispatch information.

fn bare_validate( _call: &Call, _info: &<Call as Dispatchable>::Info, _len: usize, ) -> Result<ValidTransaction, TransactionValidityError>

Validation logic for bare extrinsics.

fn bare_validate_and_prepare( _call: &Call, _info: &<Call as Dispatchable>::Info, _len: usize, ) -> Result<(), TransactionValidityError>

All pre-flight logic run before dispatching bare extrinsics.

fn bare_post_dispatch( _info: &<Call as Dispatchable>::Info, _post_info: &mut <Call as Dispatchable>::PostInfo, _len: usize, _result: &Result<(), DispatchError>, ) -> Result<(), TransactionValidityError>
