Struct Features

pub struct Features(/* private fields */);

A collection of CPU features.

An instruction is valid when any of the features in the collection are enabled; i.e., the collection is an OR expression.

let fs = Feature::_64b | Feature::compat;
assert_eq!(fs.to_string(), "_64b | compat");

Implementations

impl Features

pub fn is_empty(&self) -> bool

pub fn iter(&self) -> impl Iterator<Item = &Feature>

Trait Implementations

impl Display for Features

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<Feature> for Features

fn from(flag: Feature) -> Self

Converts to this type from the input type.

impl From<Option<Feature>> for Features

fn from(flag: Option<Feature>) -> Self

Converts to this type from the input type.

impl PartialEq for Features

fn eq(&self, other: &Features) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
