    // Required method
    fn load_from_db(

Represents an interface to load some ent from a database

Required Associated Types

type Output: Ent

The ent that will be loaded

Required Methods

fn load_from_db( db: WeakDatabaseRc, id: Id, ) -> DatabaseResult<Option<Self::Output>>

Retrieves the ent instance with the specified id from the provided database, returning none if ent not found

Provided Methods

fn load_from_db_strict( db: WeakDatabaseRc, id: Id, ) -> DatabaseResult<Self::Output>

Retrieves the ent instance with the specified id from the provided database, converting none into a missing ent error

fn load(id: Id) -> DatabaseResult<Option<Self::Output>>

Retrieves the ent instance with the specified id from the global database, returning none if ent not found

fn load_strict(id: Id) -> DatabaseResult<Self::Output>

Retrieves the ent instance with the specified id from the global database, converting none into a missing ent error

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
