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());

Implementations

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 Clone for Features

pub fn clone(&self) -> Features

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Features

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

Formats the value using the given formatter.

impl Default for Features

pub fn default() -> Features

Returns the "default value" for a type.

impl Eq for Features

impl Hash for Features

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

Feeds this value into the given Hasher.

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

Feeds a slice of this type into the given Hasher.

impl PartialEq<Features> for Features

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

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