Struct ChainedBackend 

pub struct ChainedBackend { /* private fields */ }

A backend that chains multiple backends together.

Looks up translations in order; the first backend that returns a result wins. This allows e.g. database overrides to take priority over file-based translations.

Implementations

impl ChainedBackend

pub fn new(backends: Vec<Arc<dyn Backend>>) -> Self

Create a new chained backend from an ordered list of backends.

Backends are queried in order; the first match wins.

pub fn push_front(&mut self, backend: Arc<dyn Backend>)

Add a backend to the chain (highest priority — queried first).

pub fn push_back(&mut self, backend: Arc<dyn Backend>)

Add a backend to the end of the chain (lowest priority).
