Enum PredReturn

Source

pub enum PredReturn {
    True,
    False,
    Binding(Vec<(usize, usize)>),
}

Expand description

Return type for predicate functions.

A predicate either succeeds (PredReturn::True), fails (PredReturn::False), or succeeds with variable bindings (PredReturn::Binding).

Variants§

§

True

§

False

§

Binding(Vec<(usize, usize)>)

Success with a list of (source_addr, target_addr) bindings to apply on the heap.

Implementations§
