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

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

let optimal_features = vulkano::instance::Features {
    geometry_shader: true,
    tessellation_shader: true,
    .. vulkano::instance::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
[src]

fn none() -> Features

Builds a Features object with all values to false.

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.

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.

Trait Implementations

impl Hash for Features
[src]

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

Feeds this value into the state given, updating the hasher as necessary.

fn hash_slice<H>(data: &[Self], state: &mut H) where H: Hasher
1.3.0

Feeds a slice of this type into the state provided.

fn ne(&self, __arg_0: &Features) -> bool

This method tests for !=.

impl Clone for Features
[src]

fn clone(&self) -> Features
