Enum KvInsertIntent 

pub enum KvInsertIntent {
    Insert,
    InsertIfAbsent,
    Put,
}

INSERT-vs-UPSERT intent carried on SqlPlan::KvInsert.

The KV engine’s KvOp::Put is a Redis-SET-style upsert: write wins unconditionally. SQL requires INSERT to raise unique_violation on duplicate keys, so the plan must carry the caller’s intent through to the Data Plane where the hash-index existence probe happens.

Variants

Insert

Plain INSERT: duplicate key raises SQLSTATE 23505.

InsertIfAbsent

INSERT ... ON CONFLICT DO NOTHING: duplicate key is a no-op.

Put

UPSERT / INSERT ... ON CONFLICT (key) DO UPDATE / RESP SET: duplicate key overwrites. Also the shape used by the RESP SET path.

Trait Implementations

impl Clone for KvInsertIntent

fn clone(&self) -> KvInsertIntent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KvInsertIntent

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

Formats the value using the given formatter.

impl PartialEq for KvInsertIntent

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