Struct pallet_contracts::chain_extension::Diff
source · pub struct Diff {
pub bytes_added: u32,
pub bytes_removed: u32,
pub items_added: u32,
pub items_removed: u32,
}Expand description
This type is used to describe a storage change when charging from the meter.
Fields§
§bytes_added: u32How many bytes were added to storage.
bytes_removed: u32How many bytes were removed from storage.
items_added: u32How many storage items were added to storage.
items_removed: u32How many storage items were removed from storage.
Implementations§
source§impl Diff
impl Diff
sourcepub fn update_contract<T: Config>(
&self,
info: Option<&mut ContractInfo<T>>
) -> Deposit<<<T as Config>::Currency as Inspect<<T as Config>::AccountId>>::Balance>
pub fn update_contract<T: Config>( &self, info: Option<&mut ContractInfo<T>> ) -> Deposit<<<T as Config>::Currency as Inspect<<T as Config>::AccountId>>::Balance>
Calculate how much of a charge or refund results from applying the diff and store it
in the passed info if any.
Note
In case None is passed for info only charges are calculated. This is because refunds
are calculated pro rata of the existing storage within a contract and hence need extract
this information from the passed info.

then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.§fn into_any_rc(self: Rc<T>) -> Rc<dyn Any + 'static>

further downcast into Rc<ConcreteType> where ConcreteType implements Trait.§fn as_any(&self) -> &(dyn Any + 'static)
fn as_any(&self) -> &(dyn Any + 'static)
Convert
&Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &Any’s vtable from &Trait’s.§fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
Convert
&mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &mut Any’s vtable from &mut Trait’s.source§impl<T> Instrument for T
