Enum FilterExpr 

pub enum FilterExpr {
    Filter(Filter),
    All(Vec<FilterExpr>),
    Any(Vec<FilterExpr>),
    Not(Box<FilterExpr>),
    Relation(RelationFilter),
    Coalesce(CoalesceFilter),
    Json(JsonFilter),
    VectorDistance(VectorDistanceFilter),
}

Variants

Filter(Filter)

All(Vec<FilterExpr>)

Any(Vec<FilterExpr>)

Not(Box<FilterExpr>)

Relation(RelationFilter)

Coalesce(CoalesceFilter)

COALESCE(col_a, col_b, ...) op value — built via super::coalesce::coalesce.

Json(JsonFilter)

JSON / JSONB column predicates — see JsonFilter. Built via FieldRef::json_has_key(...) and FieldRef::json_get_text(...).<cmp>(...).

VectorDistance(VectorDistanceFilter)

Vector(n) distance-to-a-query-vector threshold predicates (see docs/design/extensions.md §6/§7, cratestack#163) — see VectorDistanceFilter. Built via FieldRef::distance_to(...).lt(...)/.lte(...)/etc. PG-only (pgvector); the embedded rusqlite backend fails loud at render time, mirroring [Self::Spatial].

Implementations

impl FilterExpr

pub fn all(filters: impl IntoIterator<Item = FilterExpr>) -> Self

pub fn any(filters: impl IntoIterator<Item = FilterExpr>) -> Self

pub fn not(self) -> Self

pub fn and(self, other: impl Into<FilterExpr>) -> Self

pub fn or(self, other: impl Into<FilterExpr>) -> Self

impl FilterExpr

pub fn relation( parent_table: &'static str, parent_column: &'static str, related_table: &'static str, related_column: &'static str, filter: FilterExpr, scope: RelatedReadScope, ) -> Self

To-one: the related row exists, is visible under scope, and matches filter.

pub fn relation_some( parent_table: &'static str, parent_column: &'static str, related_table: &'static str, related_column: &'static str, filter: FilterExpr, scope: RelatedReadScope, ) -> Self

To-many some: at least one related row visible under scope matches filter.

pub fn relation_every( parent_table: &'static str, parent_column: &'static str, related_table: &'static str, related_column: &'static str, filter: FilterExpr, scope: RelatedReadScope, ) -> Self

To-many every: no related row visible under scope fails filter (vacuously true when none is visible).

pub fn relation_none( parent_table: &'static str, parent_column: &'static str, related_table: &'static str, related_column: &'static str, filter: FilterExpr, scope: RelatedReadScope, ) -> Self

To-many none: no related row visible under scope matches filter.
