Struct vulkano::RequiresOneOf

pub struct RequiresOneOf {
    pub api_version: Option<Version>,
    pub features: &'static [&'static str],
    pub device_extensions: &'static [&'static str],
    pub instance_extensions: &'static [&'static str],
}

Used in errors to indicate a set of alternatives that needs to be available/enabled to allow a given operation.

Fields

api_version: Option<Version>

A minimum Vulkan API version that would allow the operation.

features: &'static [&'static str]

Enabled features that would allow the operation.

device_extensions: &'static [&'static str]

Available/enabled device extensions that would allow the operation.

instance_extensions: &'static [&'static str]

Available/enabled instance extensions that would allow the operation.

Implementations

impl RequiresOneOf

pub fn len(&self) -> usize

Returns whether there is more than one possible requirement.

Trait Implementations

impl Clone for RequiresOneOf

fn clone(&self) -> RequiresOneOf

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RequiresOneOf

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

Formats the value using the given formatter.

impl Default for RequiresOneOf

fn default() -> RequiresOneOf

Returns the “default value” for a type.

impl Display for RequiresOneOf

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

Formats the value using the given formatter.

impl PartialEq<RequiresOneOf> for RequiresOneOf

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

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

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

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