I/O-free coroutine moving every id from from to to.

Implementations

pub fn new( root: impl Into<PathBuf>, from: &str, to: &str, ids: &[&str], ) -> Result<Self, M2dirMessageMoveError>

Trait Implementations

impl M2dirCoroutine for M2dirMessageMove

type Yield = M2dirYield

Intermediate value handed back on every step. Per-coroutine: each implementor picks exactly the variants it needs. In io-m2dir every coroutine picks M2dirYield.

type Return = Result<(), M2dirMessageMoveError>

Terminal value. By convention Result<Output, Error>; the “ok” arm carries the operation’s final output, the “error” arm carries the cause.

fn resume( &mut self, arg: Option<M2dirArg>, ) -> M2dirCoroutineState<Self::Yield, Self::Return>

Advances the coroutine one step.
