Enum FilterExpr 

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

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>(...).

Spatial(SpatialFilter)

PostGIS spatial predicates — see SpatialFilter. Built via FieldRef::covers_geography(...) / FieldRef::dwithin_geography(...). PG-only; the embedded rusqlite backend doesn’t ship SpatiaLite by default, so its renderer fails loud at codegen time.

Trait Implementations

impl Clone for FilterExpr

fn clone(&self) -> FilterExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FilterExpr

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

Formats the value using the given formatter.

impl From<Filter> for FilterExpr

fn from(value: Filter) -> FilterExpr

Converts to this type from the input type.

impl PartialEq for FilterExpr

fn eq(&self, other: &FilterExpr) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
