Struct DeleteMany 

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

Implementations

impl<'a, M: 'static, PK: 'static> DeleteMany<'a, M, PK>

pub fn where_(self, filter: Filter) -> Self

pub fn where_expr(self, filter: FilterExpr) -> Self

pub fn where_any(self, filters: impl IntoIterator<Item = FilterExpr>) -> Self

pub fn where_optional<F>(self, filter: Option<F>) -> Self

where F: Into<FilterExpr>,

Conditionally append a filter; None is a no-op.

pub fn preview_sql(&self) -> String

Approximate SQL preview. The runtime path interpolates filter predicates and the delete policy clause; this returns the rough shape for migration tooling and the schema studio.

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

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

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,
