Represents all the features that are available on a physical device or enabled on a logical device.

Note that the robust_buffer_access is guaranteed to be supported by all Vulkan implementations.

Example

use vulkano::device::Features;
let minimal_features = Features {
    geometry_shader: true,
    .. Features::none()
};

let optimal_features = vulkano::device::Features {
    geometry_shader: true,
    tessellation_shader: true,
    .. Features::none()
};

if !physical_device.supported_features().superset_of(&minimal_features) {
    panic!("The physical device is not good enough for this application.");
}

assert!(optimal_features.superset_of(&minimal_features));
let features_to_request = optimal_features.intersection(physical_device.supported_features());

Methods

impl Features

pub fn none() -> Features

Builds a Features object with all values to false.

pub fn all() -> Features

Builds a Features object with all values to true.

Note: This function is used for testing purposes, and is probably useless in a real code.

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

Returns true if self is a superset of the parameter.

That is, for each feature of the parameter that is true, the corresponding value in self is true as well.

pub fn intersection(&self, other: &Features) -> Features

Builds a Features that is the intersection of self and another Features object.

The result's field will be true if it is also true in both self and other.

pub fn difference(&self, other: &Features) -> Features

Builds a Features that is the difference of another Features object from self.

The result's field will be true if it is true in self but not other.

Trait Implementations

impl PartialEq<Features> for Features

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Eq for Features

impl Clone for Features

fn clone(&self) -> Features

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Hash for Features

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, 

Feeds a slice of this type into the given [Hasher].

impl Debug for Features

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

Formats the value using the given formatter.
