pub struct CheckWeight<T: Config + Send + Sync>(_);
Expand description

Block resource (weight) limit check.

Transaction Validity

This extension does not influence any fields of TransactionValidity in case the transaction is valid.

Implementations§

source§

impl<T: Config + Send + Sync> CheckWeight<T>where T::RuntimeCall: Dispatchable<Info = DispatchInfo, PostInfo = PostDispatchInfo>,

source

pub fn new() -> Self

Creates new SignedExtension to check weight of the extrinsic.

source

pub fn do_pre_dispatch( info: &DispatchInfoOf<T::RuntimeCall>, len: usize ) -> Result<(), TransactionValidityError>

Do the pre-dispatch checks. This can be applied to both signed and unsigned.

It checks and notes the new weight and length.

source

pub fn do_validate( info: &DispatchInfoOf<T::RuntimeCall>, len: usize ) -> TransactionValidity

Do the validate checks. This can be applied to both signed and unsigned.

It only checks that the block weight and length limit will not exceed.
