Expand description

SQLx lowerer for gatekeep residual policies.

Implementations§

Source§

impl<B, P> SqlxLowerer<B, P, OrdinalProjection>
where B: GatekeepSqlxBackend,

Source

pub const fn new(predicates: P) -> Self

Builds a lowerer using ordinal grade projection.

Source§

impl<B, P, M> SqlxLowerer<B, P, M>
where B: GatekeepSqlxBackend,

Source

pub const fn with_projection(predicates: P, projection: M) -> Self

Builds a lowerer using a caller-supplied projection strategy.

Source

pub fn lower_filter<O>( &self, residual: &ResidualPolicy<O>, cx: &Context, ) -> Result<SqlxFragment<B>, LowerError>
where P: SqlxFactPredicates<B>,

Lowers only the Boolean filter. This works for every outcome lattice.
