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

impl Features[src]

pub fn none() -> Features[src]

Builds a Features object with all values to false.

pub fn all() -> Features[src]

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[src]

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[src]

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[src]

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.
