Enum FilterFn 

pub enum FilterFn<E: EntityTrait> {
    ValueOnly(fn(Select<E>, Option<String>) -> Select<E>),
    WithOp(fn(Select<E>, Option<String>, Option<ActixAdminFilterOperator>) -> Select<E>),
}

Storage for the filter callback. Two shapes are supported so that simple value-only filters remain a one-liner, while operator-aware filters can react to the user’s chosen comparator.

Variants

ValueOnly(fn(Select<E>, Option<String>) -> Select<E>)

WithOp(fn(Select<E>, Option<String>, Option<ActixAdminFilterOperator>) -> Select<E>)

Implementations

impl<E: EntityTrait> FilterFn<E>

pub fn apply( &self, query: Select<E>, value: Option<String>, operator: Option<ActixAdminFilterOperator>, ) -> Select<E>

Apply the underlying callback to query. Operator-only closures receive operator; value-only closures ignore it.
