Struct PredicateView

pub struct PredicateView<'a>(/* private fields */);
Expand description

A reference to just the boolean predicates of a settings object.

The settings objects themselves are generated and appear in the isa/*/settings.rs modules. Each settings object provides a predicate_view() method that makes it possible to query ISA predicates by number.

Implementations§

§

impl<'a> PredicateView<'a>

pub fn new(bits: &'a [u8]) -> PredicateView<'a>

Create a new view of a precomputed predicate vector.

See the predicate_view() method on the various Flags types defined for each ISA.

pub fn test(self, p: usize) -> bool

Check a numbered predicate.
