Struct LoadedState 

pub struct LoadedState { /* private fields */ }

A loaded store state whose write worker has not been started yet.

Returned by State::load. Self::start spawns the writer and yields the read-only State together with the write capabilities; since this is the only way to obtain a BlockWriter, BlockWriter::apply_block can always make progress.

Implementations

impl LoadedState

pub fn start( self, shutdown: CancellationToken, ) -> (Arc<State>, BlockWriter, ProofWriter, WriterTask)

Spawns the write worker onto the current runtime and returns the read-only state together with the write capabilities and the writer task’s handle.

Arc<State> is the read-only view shared with every component that queries or subscribes; it exposes no mutating methods. BlockWriter and ProofWriter are the only handles able to mutate the store — hand them to the single task driving each write path (block production or sync, and proof scheduling or sync respectively). The capabilities expose no read access: tasks that both read and write receive the Arc<State> alongside their capability.

The writer exits once shutdown is cancelled or the BlockWriter (holding the only request sender) is dropped — an in-flight block write always completes first. Awaiting the returned handle after either event guarantees the writer has released the tree storage it owns; a join error carries a writer panic.

Callers without a token to cancel should pass CancellationToken::new and stop the store via BlockWriter::stop instead of dropping and joining by hand.
