where SE: SignedExtension + Decode,

fn decode<__CodecInputEdqy>( __codec_input_edqy: &mut __CodecInputEdqy, ) -> Result<AsTransactionExtension<SE>, Error>

where __CodecInputEdqy: Input,

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<SE> Default for AsTransactionExtension<SE>

where SE: SignedExtension + Default,

fn default() -> AsTransactionExtension<SE>

Returns the “default value” for a type.

impl<SE> Encode for AsTransactionExtension<SE>

where SE: SignedExtension + Encode,

fn size_hint(&self) -> usize

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

fn encode_to<__CodecOutputEdqy>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy, )

where __CodecOutputEdqy: Output + ?Sized,

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>( &self, f: __CodecUsingEncodedCallback, ) -> __CodecOutputReturn

where __CodecUsingEncodedCallback: FnOnce(&[u8]) -> __CodecOutputReturn,

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

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl<SE> From<SE> for AsTransactionExtension<SE>

where SE: SignedExtension,

fn from(value: SE) -> AsTransactionExtension<SE>

Converts to this type from the input type.

impl<SE> PartialEq for AsTransactionExtension<SE>

where SE: PartialEq + SignedExtension,

fn eq(&self, other: &AsTransactionExtension<SE>) -> 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<SE> TransactionExtension<<SE as SignedExtension>::Call> for AsTransactionExtension<SE>

where SE: SignedExtension, <<SE as SignedExtension>::Call as Dispatchable>::RuntimeOrigin: AsSystemOriginSigner<<SE as SignedExtension>::AccountId> + Clone,

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

Unique identifier of this signed extension.

type Implicit = <SE as SignedExtension>::AdditionalSigned

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<<AsTransactionExtension<SE> as TransactionExtension<<SE as SignedExtension>::Call>>::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.

fn metadata() -> Vec<TransactionExtensionMetadata>

Returns the metadata for this extension.

fn weight(&self, _call: &<SE as SignedExtension>::Call) -> Weight

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

type Val = ()

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

type Pre = <SE as SignedExtension>::Pre

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

fn validate( &self, origin: <<SE as SignedExtension>::Call as Dispatchable>::RuntimeOrigin, call: &<SE as SignedExtension>::Call, info: &<<SE as SignedExtension>::Call as Dispatchable>::Info, len: usize, _self_implicit: <AsTransactionExtension<SE> as TransactionExtension<<SE as SignedExtension>::Call>>::Implicit, _inherited_implication: &impl Encode, _source: TransactionSource, ) -> Result<(ValidTransaction, <AsTransactionExtension<SE> as TransactionExtension<<SE as SignedExtension>::Call>>::Val, <<SE as SignedExtension>::Call as Dispatchable>::RuntimeOrigin), TransactionValidityError>

Validate a transaction for the transaction queue.

fn prepare( self, _: (), origin: &<<SE as SignedExtension>::Call as Dispatchable>::RuntimeOrigin, call: &<SE as SignedExtension>::Call, info: &<<SE as SignedExtension>::Call as Dispatchable>::Info, len: usize, ) -> Result<<AsTransactionExtension<SE> as TransactionExtension<<SE as SignedExtension>::Call>>::Pre, TransactionValidityError>

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

fn post_dispatch_details( pre: <AsTransactionExtension<SE> as TransactionExtension<<SE as SignedExtension>::Call>>::Pre, info: &<<SE as SignedExtension>::Call as Dispatchable>::Info, post_info: &<<SE as SignedExtension>::Call as Dispatchable>::PostInfo, len: usize, result: &Result<(), DispatchError>, ) -> Result<Weight, TransactionValidityError>

Do any post-flight stuff for an extrinsic.

fn bare_validate( call: &<SE as SignedExtension>::Call, info: &<<SE as SignedExtension>::Call as Dispatchable>::Info, len: usize, ) -> Result<ValidTransaction, TransactionValidityError>

Validation logic for bare extrinsics.

fn bare_validate_and_prepare( call: &<SE as SignedExtension>::Call, info: &<<SE as SignedExtension>::Call as Dispatchable>::Info, len: usize, ) -> Result<(), TransactionValidityError>

All pre-flight logic run before dispatching bare extrinsics.

fn bare_post_dispatch( info: &<<SE as SignedExtension>::Call as Dispatchable>::Info, post_info: &mut <<SE as SignedExtension>::Call as Dispatchable>::PostInfo, len: usize, result: &Result<(), DispatchError>, ) -> Result<(), TransactionValidityError>

Post dispatch logic run after dispatching bare extrinsics.

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.

impl<SE> TypeInfo for AsTransactionExtension<SE>

where SE: SignedExtension + TypeInfo + 'static,

type Identity = AsTransactionExtension<SE>
