Struct DatabaseFromEngine 

pub struct DatabaseFromEngine { /* private fields */ }

Built-in evaluator: look up logical_name + engine_id on a DatabaseRouter.

Composes crate::router_key() then DatabaseRouter::resolve.

Examples

use valence_backend_mem::ENGINE_ID;
use valence_core::{Database, DatabaseEvaluator};

let db = Database::from_engine("default", ENGINE_ID);
assert_eq!(db.logical_name(), "default");
assert_eq!(db.engine_id(), ENGINE_ID);
