Struct frame_system::CheckWeight
source · pub struct CheckWeight<T: Config + Send + Sync>(/* private fields */);
Expand description
Block resource (weight) limit check.
§Transaction Validity
This extension does not influence any fields of TransactionValidity
in case the
transaction is valid.

impl<T: Config + Send + Sync> CheckWeight<T>
sourcepub fn do_pre_dispatch(
info: &DispatchInfoOf<T::RuntimeCall>,
len: usize
) -> Result<(), TransactionValidityError>
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.
sourcepub fn do_validate(
info: &DispatchInfoOf<T::RuntimeCall>,
len: usize
) -> TransactionValidity
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.
