Struct DisallowSigned

pub struct DisallowSigned;

Simple implementation which fails any transaction which is signed.

Trait Implementations

impl Clone for DisallowSigned

fn clone(&self) -> DisallowSigned

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DisallowSigned

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

Formats the value using the given formatter.

impl Decode for DisallowSigned

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 Default for DisallowSigned

fn default() -> DisallowSigned

Returns the “default value” for a type.

impl Encode for DisallowSigned

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 PartialEq for DisallowSigned

fn eq(&self, other: &DisallowSigned) -> 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 SignedExtension for DisallowSigned

const IDENTIFIER: &'static str = "DisallowSigned"

Unique identifier of this signed extension.

type AccountId = <<MultiSignature as Verify>::Signer as IdentifyAccount>::AccountId

The type which encodes the sender identity.

type Call = 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 pre_dispatch( self, who: &Self::AccountId, call: &Self::Call, info: &DispatchInfoOf<Self::Call>, len: usize, ) -> Result<Self::Pre, TransactionValidityError>

Do any pre-flight stuff for a signed transaction.

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 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 TypeInfo for DisallowSigned

type Identity = DisallowSigned

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
