len: usize,
) -> Result<(ValidTransaction, u32), TransactionValidityError>
pub fn do_validate( info: &DispatchInfoOf<T::RuntimeCall>, len: usize, ) -> Result<(ValidTransaction, u32), TransactionValidityError>
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.
Returns the transaction validity and the next block length, to be used in prepare
.
sourcepub fn do_prepare(
info: &DispatchInfoOf<T::RuntimeCall>,

next_len: u32,
) -> Result<(), TransactionValidityError>
pub fn do_prepare( info: &DispatchInfoOf<T::RuntimeCall>, len: usize, next_len: u32, ) -> 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.

§type Implicit = ()
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”.source§fn weight(&self, _: &T::RuntimeCall) -> Weight
fn weight(&self, _: &T::RuntimeCall) -> Weight

but instead of executing the call, execute
substitute
instead. Since this doesn’t actually
dispatch the call, it doesn’t need to consume it and so call
