Struct cranelift_codegen::settings::PredicateView

pub struct PredicateView<'a>(_);

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]) -> Self

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.

Trait Implementations

impl<'a> Clone for PredicateView<'a>

fn clone(&self) -> PredicateView<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Hash for PredicateView<'a>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,
    Self: Sized,

Feeds a slice of this type into the given Hasher.
