pub struct FileLedger { /* private fields */ }Expand description
A crash-safe file-backed ledger: the send cursor is written to a temp file, fsync’d, then renamed over the target, so a restart resumes past every offset ever handed to a caller and a crash leaves either the old cursor or the new one, never a torn value. Native-only (the relay path is native-only); a browser peer would journal the cursor through the OPFS VFS.

then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.§fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

fn as_any(&self) -> &(dyn Any + 'static)
Convert
&Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot

Convert
&mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &mut Any’s vtable from &mut Trait’s.
