Trait BackingStorage

pub trait BackingStorage: BackingStorageSealed {
    // Required method
    fn invalidate(&self, reason_code: &str) -> Result<()>;
}

Represents types accepted by TurboTasksBackend::new. Typically this is the value returned by default_backing_storage or noop_backing_storage.

This trait is sealed. External crates are not allowed to implement it.

Required Methods

fn invalidate(&self, reason_code: &str) -> Result<()>

Called when the database should be invalidated upon re-initialization.

This typically means that we’ll restart the process or turbo-tasks soon with a fresh database. If this happens, there’s no point in writing anything else to disk, or flushing during KeyValueDatabase::shutdown.

This can be implemented by calling invalidate_db with the database’s non-versioned base path.

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.
