Trait AccessRightsPersistence 

pub trait AccessRightsPersistence: Send + Sync {
    // Required methods
    fn load(
        &self,
        rights: ObjectIdentifier,
    ) -> Result<Option<AccessRightsSnapshot>, Error>;
    fn save(
        &self,
        rights: ObjectIdentifier,
        snapshot: &AccessRightsSnapshot,
    ) -> Result<(), Error>;
}

Application-owned storage for one Access Rights object’s rule arrays, Enable and Accompaniment.

The object calls it from its writer thread, one call at a time. A written value lands in storage a moment before the object serves it: see storage leads the served state.

Required Methods

fn load( &self, rights: ObjectIdentifier, ) -> Result<Option<AccessRightsSnapshot>, Error>

What was last saved for rights, or None when nothing was saved.

fn save( &self, rights: ObjectIdentifier, snapshot: &AccessRightsSnapshot, ) -> Result<(), Error>

Durably replace what is saved for rights with snapshot.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
