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

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

pub fn size_hint(&self) -> usize

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

impl<T: Trait + Send + Sync> EncodeLike<CheckWeight<T>> for CheckWeight<T> where
    PhantomData<T>: Encode,
    PhantomData<T>: Encode, 

impl<T: Eq + Trait + Send + Sync> Eq for CheckWeight<T>

impl<T: PartialEq + Trait + Send + Sync> PartialEq<CheckWeight<T>> for CheckWeight<T>

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

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

fn ne(&self, other: &CheckWeight<T>) -> bool

This method tests for !=.

impl<T: Trait + Send + Sync> SignedExtension for CheckWeight<T> where
    T::Call: Dispatchable<Info = DispatchInfo, PostInfo = PostDispatchInfo>, 

type AccountId = T::AccountId

The type which encodes the sender identity.

type Call = T::Call

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.

const IDENTIFIER: &'static str

Unique identifier of this signed extension.

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<(), 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 pre_dispatch_unsigned(
    _call: &Self::Call,
    info: &DispatchInfoOf<Self::Call>,
    len: usize
) -> Result<(), TransactionValidityError>

Do any pre-flight stuff for a unsigned transaction.

fn validate_unsigned(
    _call: &Self::Call,
    info: &DispatchInfoOf<Self::Call>,
    len: usize
) -> TransactionValidity

Validate an unsigned transaction for the transaction queue.

fn post_dispatch(
    _pre: Self::Pre,
    info: &DispatchInfoOf<Self::Call>,
    post_info: &PostDispatchInfoOf<Self::Call>,
    _len: usize,
    result: &DispatchResult
) -> Result<(), TransactionValidityError>

Do any post-flight stuff for an extrinsic.

pub fn identifier() -> Vec<&'static str, Global>

Returns the list of unique identifier for this signed extension.
