Trait Implementations

impl<T> Operator<T> for EqImpl<T> where
    T: Eq, 

fn apply(&self, value: &T) -> bool

Apply this operator a single value, producing a true/false result.

fn empty_collection(&self) -> bool

Return a value for this operator when applied to an empty collection. Implicitly, operators are distributed over collections with any semantics, so that any true result means the collection evaluates to true. The default behaviour for this method is to return false, which is consistent with those semantics.

fn null_option(&self) -> bool

Return a value for this operator when applied to a None value wrapping its target type (e.g. for an operator on T, we are determining the behaviour on Option). This is required because we automatically implement all operators on Option, but in rare cases the operator’s behaviour isn’t well captured by returning false for None (e.g. `isnull).
