Enum OnConflictAction 

pub enum OnConflictAction {
    DoNothing,
    DoUpdate {
        assignments: Vec<(String, UpsertExpr)>,
    },
}

The action to take when ON CONFLICT (target) fires.

Variants

DoNothing

DO NOTHING — no mutation, rowsAffected = 0, but the audit log still records the upsert attempt (via AuditAction::UpsertApplied with resolution NoOp).

DoUpdate

DO UPDATE SET col = <expr>, ... — replace the conflicting row with the result of evaluating each assignment. EXCLUDED.col references the value from the would-be-inserted row.

Fields

assignments: Vec<(String, UpsertExpr)>

Column assignments. EXCLUDED.col references are represented as UpsertExpr::Excluded(col) so the tenant-layer dispatcher can substitute values from the INSERT’s row payload.

Trait Implementations

impl Clone for OnConflictAction

fn clone(&self) -> OnConflictAction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OnConflictAction

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

Formats the value using the given formatter.

impl PartialEq for OnConflictAction

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