Struct pallet_assets::ExtraMutator

source ·

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

Expand description

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.
