Implementations

impl<Runtime> SubspaceExtension<Runtime>

pub fn new() -> Self

Trait Implementations

impl<Runtime: Clone> Clone for SubspaceExtension<Runtime>

fn clone(&self) -> SubspaceExtension<Runtime>

Returns a copy of the value.

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

Performs copy-assignment from source.

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

Formats the value using the given formatter.

impl<Runtime> Decode for SubspaceExtension<Runtime>

where PhantomData<Runtime>: 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<Runtime> Default for SubspaceExtension<Runtime>

fn default() -> Self

Returns the “default value” for a type.

impl<Runtime> Encode for SubspaceExtension<Runtime>

where PhantomData<Runtime>: 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<__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<Runtime: PartialEq> PartialEq for SubspaceExtension<Runtime>

fn eq(&self, other: &SubspaceExtension<Runtime>) -> 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<Runtime> TransactionExtension<<Runtime as Config>::RuntimeCall> for SubspaceExtension<Runtime>

where Runtime: Config + TypeInfo + Debug + Send + Sync, <RuntimeCallFor<Runtime> as Dispatchable>::RuntimeOrigin: AsSystemOriginSigner<<Runtime as Config>::AccountId> + Clone, RuntimeCallFor<Runtime>: MaybeSubspaceCall<Runtime>,

const IDENTIFIER: &'static str = "SubspaceExtension"

Unique identifier of this signed extension.

type 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”.

type Val = ExtensionWeightData

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

type Pre = ExtensionWeightData

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

fn weight(&self, call: &RuntimeCallFor<Runtime>) -> Weight

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

fn validate( &self, origin: DispatchOriginOf<RuntimeCallFor<Runtime>>, call: &RuntimeCallFor<Runtime>, _info: &DispatchInfoOf<RuntimeCallFor<Runtime>>, _len: usize, _self_implicit: Self::Implicit, _inherited_implication: &impl Implication, source: TransactionSource, ) -> ValidateResult<Self::Val, RuntimeCallFor<Runtime>>

Validate a transaction for the transaction queue.

fn prepare( self, val: Self::Val, _origin: &DispatchOriginOf<RuntimeCallFor<Runtime>>, _call: &RuntimeCallFor<Runtime>, _info: &DispatchInfoOf<RuntimeCallFor<Runtime>>, _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<RuntimeCallFor<Runtime>>, _post_info: &PostDispatchInfoOf<RuntimeCallFor<Runtime>>, _len: usize, _result: &DispatchResult, ) -> Result<Weight, TransactionValidityError>

Do any post-flight stuff for an extrinsic.

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.

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>

Post dispatch logic run after dispatching bare extrinsics.

impl<Runtime> TypeInfo for SubspaceExtension<Runtime>

where PhantomData<Runtime>: TypeInfo + 'static, Runtime: TypeInfo + 'static,

type Identity = SubspaceExtension<Runtime>

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
