Struct UpdateManySet 

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

Implementations

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

where I: UpdateModelInput<M>,

pub fn preview_sql(&self) -> String

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

where for<'r> M: Send + Unpin + FromRow<'r, PgRow> + Serialize,

Returns BatchSummary { total, ok, err } where total = ok = rows actually updated and err = 0. Statement-level failures surface as the outer Err.

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

where for<'r> M: Send + Unpin + FromRow<'r, PgRow> + Serialize,

Run inside a caller-supplied transaction. Audit + outbox writes land in tx; caller commits.

Trait Implementations

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

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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

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

Formats the value using the given formatter.
