Struct UpsertRecordDoNothing 

pub struct UpsertRecordDoNothing<'a, M: 'static, PK: 'static, I> { /* private fields */ }

Implementations

impl<'a, M: 'static, PK: 'static, I> UpsertRecordDoNothing<'a, M, PK, I>

where I: UpsertModelInput<M>,

pub fn on_conflict(self, target: ConflictTarget) -> Self

Choose the conflict target. See super::upsert::UpsertRecord::on_conflict; works identically here, and can be called either before or after .do_nothing().

pub fn preview_sql(&self) -> String

Render an approximate SQL preview of the insert-branch statement. The actual call wraps a SELECT ... FOR UPDATE probe around it and may perform a fallback SELECT on a lost race — see UpsertOutcome for the full sequencing.

pub async fn run(self, ctx: &CoolContext) -> Result<UpsertOutcome<M>, CoolError>

where for<'r> M: Send + Unpin + FromRow<'r, PgRow> + Serialize, PK: Send + Type<Postgres> + for<'q> Encode<'q, Postgres>,

pub async fn run_in_tx<'tx>( self, tx: &mut Transaction<'tx, Postgres>, ctx: &CoolContext, ) -> Result<UpsertOutcome<M>, CoolError>

where for<'r> M: Send + Unpin + FromRow<'r, PgRow> + Serialize, PK: Send + Type<Postgres> + for<'q> Encode<'q, Postgres>,

Like Self::run but participates in a caller-supplied transaction. The conflict probe (and, on the insert branch, the ON CONFLICT DO NOTHING) run against tx, so any row lock is held until the caller commits. The event outbox is not drained here.

impl<'a, M: Clone + 'static, PK: Clone + 'static, I: Clone> Clone for UpsertRecordDoNothing<'a, M, PK, I>

fn clone(&self) -> UpsertRecordDoNothing<'a, M, PK, I>

Returns a duplicate of the value.

impl<'a, M: Debug + 'static, PK: Debug + 'static, I: Debug> Debug for UpsertRecordDoNothing<'a, M, PK, I>
