AllCommitted

Struct AllCommitted

pub struct AllCommitted;

Expand description

An oracle that reports every version as committed. Equivalent to the pre-Phase-C.2 two-state world; lets a caller that does not yet track aborts reuse Snapshot::visible_with_status and get behaviour identical to Snapshot::visible.

Trait Implementations§

impl Clone for AllCommitted

fn clone(&self) -> AllCommitted

Returns a duplicate of the value. Read more

1.0.0 (const: unstable) · Source§

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source. Read more

impl Copy for AllCommitted

impl Debug for AllCommitted

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter. Read more

impl Default for AllCommitted

fn default() -> AllCommitted

Returns the “default value” for a type. Read more

impl XactStatusOracle for AllCommitted

fn status(&self, _version: u64) -> XactStatus

Terminal status of version. Implementations return XactStatus::Committed for any version they no longer track (pruned below oldest_active, or frozen) — those are, by definition, committed-and-old.
