Enum PutOutcome 

pub enum PutOutcome {
    Inserted,
    Updated,
    Upserted,
    Deduped,
}

Outcome of writing a single node or edge.

Inserted and Updated are precise only for stores that can cheaply distinguish create from replace. Remote upsert-oriented backends commonly return Upserted because doing otherwise would require an extra read or a backend-specific write primitive. Portable callers should treat all three written outcomes as success and should not rely on Inserted or Updated unless they are intentionally targeting a backend that documents those precise outcomes.

Variants

Inserted

The element did not exist before and was created.

Updated

An element with the same identity existed and was overwritten or merged.

Upserted

The element was written by an upsert and the backend cannot tell whether it was an insert or an update.

Deduped

The element was dropped by a dedupe policy and nothing was written.

Implementations

impl PutOutcome

pub fn written(self) -> bool

True unless the element was deduped away.

Trait Implementations

impl Clone for PutOutcome

fn clone(&self) -> PutOutcome

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PutOutcome

impl Debug for PutOutcome

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PutOutcome

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for PutOutcome

impl PartialEq for PutOutcome

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

impl Serialize for PutOutcome

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
