Struct pallet_assets::ExtraMutator[][src]

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

Implementations

Commit any changes to storage.

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

Trait Implementations

Dereferences the value.

Mutably dereferences the value.

Checks if self is actually part of its subset T (and can be converted to it).

Use with care! Same as self.to_subset but without any property checks. Always succeeds.
