Struct CommitAck 

pub struct CommitAck { /* private fields */ }

Handle returned by DonaDbX::commit().

After a commit() call, the active log is atomically swapped and the Rayon fold pool begins computing the new state root in the background. CommitAck lets callers synchronise with that computation.

• Call wait() to block until the fold completes and obtain the 32-byte state root. Use this at the end of a block when you need the root before producing a block header.
• Call try_poll() to check without blocking whether the fold has finished. Useful in async runtimes or polling loops where blocking is undesirable.

The #[must_use] attribute ensures that accidentally discarding an ack (and therefore never waiting for the fold) produces a compiler warning.

Implementations

impl CommitAck

pub fn wait(self) -> [u8; 32]

Block until the async fold completes and return the 32-byte state root.

If the fold thread panicked or the channel was dropped, returns an all-zero sentinel value rather than propagating the error.

pub fn try_poll(&self) -> Option<[u8; 32]>

Non-blocking poll. Returns Some(root) if the fold has finished, None if it is still running.
