Struct pallet_assets::ExtraMutator

pub struct ExtraMutator<T: Config<I>, I: 'static = ()> { /* private fields */ }

A mutator type allowing inspection and possible modification of the extra “sidecar” data.

This may be used as a Deref for the pallet’s extra data. If mutated (using DerefMut), then any uncommitted changes (see commit function) will be automatically committed to storage when dropped. Changes, even after committed, may be reverted to their original values with the revert function.

Implementations

impl<T: Config<I>, I: 'static> ExtraMutator<T, I>

pub fn commit(&mut self) -> Result<(), ()>

Commit any changes to storage.

pub fn revert(self) -> Result<(), ()>

Revert any changes, even those already committed by self and drop self.
