Enum CommitOutcome 

#[non_exhaustive]
pub enum CommitOutcome {
    Empty,
    Committed(CommitSeq),
}

The durable result of a Db::write: whether a frame landed, and at which commit sequence.

Performance

Copying this value is O(1).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Empty

The transaction made no changes; no WAL frame was appended.

Committed(CommitSeq)

A durable frame landed at this commit sequence.

Trait Implementations

impl Clone for CommitOutcome

fn clone(&self) -> CommitOutcome

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CommitOutcome

impl Debug for CommitOutcome

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

Formats the value using the given formatter.

impl Eq for CommitOutcome

impl PartialEq for CommitOutcome

fn eq(&self, other: &CommitOutcome) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
