Struct piston::Api

pub struct Api {
    pub api: Cow<'static, str>,
    pub major: u32,
    pub minor: u32,
}

Stores graphics API version.

Fields

api: Cow<'static, str>

A string identifying the API.

major: u32

Major version.

minor: u32

Minor version.

Methods

impl Version

pub fn opengl(major: u32, minor: u32) -> Version

Creates a new OpenGL version.

pub fn vulkan(major: u32, minor: u32) -> Version

Creates a new Vulkan version.

pub fn directx(major: u32, minor: u32) -> Version

Creates a new DirectX version.

pub fn metal(major: u32, minor: u32) -> Version

Creates a new Metal version.

pub fn is_opengl(&self) -> bool

Returns true if the API is OpenGL, false otherwise.

pub fn is_vulkan(&self) -> bool

Returns true if the API is Vulkan, false otherwise.

pub fn is_directx(&self) -> bool

pub fn is_metal(&self) -> bool

Returns true if the API is metal, false otherwise.

Trait Implementations

impl Eq for Version

impl PartialEq<Version> for Version

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

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

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

This method tests for !=.

impl Clone for Version

fn clone(&self) -> Version

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Version

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

Formats the value using the given formatter.

impl PartialOrd<Version> for Version

fn partial_cmp(&self, other: &Version) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Version) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Version) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Version) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Version) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Ord for Version

fn cmp(&self, other: &Version) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.
