Enum cogl::Driver

#[non_exhaustive]
pub enum Driver {
    Any,
    Nop,
    Gl,
    Gl3,
    Gles1,
    Gles2,
    Webgl,
    // some variants omitted
}

Identifiers for underlying hardware drivers that may be used by Cogl for rendering.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Any

Implies no preference for which driver is used

Nop

A No-Op driver.

Gl

An OpenGL driver.

Gl3

An OpenGL driver using the core GL 3.1 profile

Gles1

An OpenGL ES 1.1 driver.

Gles2

An OpenGL ES 2.0 driver.

Webgl

A WebGL driver.

impl Ord for Driver

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

This method returns an Ordering between self and other.

#[must_use]

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

Compares and returns the maximum of two values.

#[must_use]

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

Compares and returns the minimum of two values.

#[must_use]

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

Restrict a value to a certain interval.

impl PartialEq<Driver> for Driver

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

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

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

This method tests for !=.

impl PartialOrd<Driver> for Driver

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

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

#[must_use]

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

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

#[must_use]

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

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

#[must_use]

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

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

#[must_use]

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