Struct DatabaseRouter 

pub struct DatabaseRouter { /* private fields */ }

Maps compound router keys to concrete DatabaseBackend implementations.

Keys look like inmemory_mem:default or acme_vault:billing — see crate::router_key().

Examples

use std::sync::Arc;
use valence_backend_mem::{InMemoryBackend, ENGINE_ID};
use valence_core::{router_key, DatabaseRouter};

let mut router = DatabaseRouter::new();
let key = router_key("default", ENGINE_ID);
router.register(key.clone(), Arc::new(InMemoryBackend::new()));
assert_eq!(router.resolve(&key).unwrap().engine_id(), ENGINE_ID);

Implementations

impl DatabaseRouter

pub fn new() -> Self

pub fn register( &mut self, key: impl Into<String>, backend: Arc<dyn DatabaseBackend>, )

pub fn register_runtime( &self, key: impl Into<String>, backend: Arc<dyn DatabaseBackend>, ) -> Result<()>

pub fn resolve(&self, key: &str) -> Result<Arc<dyn DatabaseBackend>>

pub fn len(&self) -> Result<usize>

pub fn is_empty(&self) -> Result<bool>

Trait Implementations

impl Default for DatabaseRouter

fn default() -> DatabaseRouter
