Expand description

A target: what a write or a read addresses and a commit makes durable, defined by the contract’s obligations and by what it reports here (DI-D-50).

A target is not where its I/O runs: the backend it is attached to runs that, by whatever means it has to reach what backs the target.

Required Methods§

Source

fn flush_domains(&self) -> &[FlushDomain]

Every flush domain its writes depend on. The declaration must be complete; an extra domain is safe, a missing one is not. None means it shares fate with every target.
