Trait Pred 

pub trait Pred<T: DeepView>: SpecPred<T::V> {
    // Required method
    exec fn test(&self, value: &T) -> ok : bool;
}

Executable counterpart of crate::core::spec::SpecPred.

The executable method takes &T so callers can validate parsed values without moving them.

Required Methods

exec fn test(&self, value: &T) -> ok : bool

ensures

ok == self.apply(value.deep_view()),

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementations on Foreign Types
