UpdateControlFlow

vstd::atomic

Enum UpdateControlFlow 

Source 
pub enum UpdateControlFlow {
    Commit,
    Abort,
}
Expand description

The control flow corresponding to the atomic update output.

Variants§

§

Commit

The update output value indicates that the atomic update has been committed.

This means try_open_atomic_update will consume the atomic update (i.e. return Ok(())), and the atomic function call has to break.

§

Abort

The update output value indicates that the atomic update has been aborted.

This means try_open_atomic_update will give back the atomic update (i.e. return Err(Tracked(au))), and the atomic function call has to continue.

Implementations§

Source§

impl UpdateControlFlow

Source

pub open spec fn is_commit(self) -> bool

{
    match self {
        UpdateControlFlow::Commit => true,
        UpdateControlFlow::Abort => false,
    }
}
Source

pub open spec fn is_abort(self) -> bool

{ !self.is_commit() }
