Enum StoreResult 

pub enum StoreResult {
    Appended,
    AlreadyExists,
}

Result of a store operation (for idempotency).

Same UsageEventId repeated append should return AlreadyExists (side effects happen only once).

Variants

Appended

First-time write.

AlreadyExists

Idempotent duplicate: already exists, not re-written.

Trait Implementations

impl Clone for StoreResult

fn clone(&self) -> StoreResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StoreResult

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

Formats the value using the given formatter.

impl PartialEq for StoreResult

fn eq(&self, other: &StoreResult) -> 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.
