Enum Gles3MinorVersion

pub enum Gles3MinorVersion {
    Automatic,
    Version0,
    Version1,
    Version2,
}

Selects which OpenGL ES 3 minor version to request.

When using ANGLE as an OpenGL ES/EGL implementation, explicitly requesting Version1 can provide a non-conformant ES 3.1 on APIs like D3D11.

Variants

Automatic

No explicit minor version is requested, the driver automatically picks the highest available.

Version0

Request an ES 3.0 context.

Version1

Request an ES 3.1 context.

Version2

Request an ES 3.2 context.

Implementations

impl Gles3MinorVersion

pub fn from_env() -> Option<Gles3MinorVersion>

Choose which minor OpenGL ES version to use from the environment variable WGPU_GLES_MINOR_VERSION.

Possible values are 0, 1, 2 or automatic. Case insensitive.

Use with unwrap_or_default() to get the default value if the environment variable is not set.

pub fn with_env(self) -> Gles3MinorVersion

Takes the given compiler, modifies it based on the WGPU_GLES_MINOR_VERSION environment variable, and returns the result.

See from_env for more information.

Trait Implementations

impl Clone for Gles3MinorVersion

fn clone(&self) -> Gles3MinorVersion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Gles3MinorVersion

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

Formats the value using the given formatter.

impl Default for Gles3MinorVersion

fn default() -> Gles3MinorVersion

Returns the “default value” for a type.

impl Hash for Gles3MinorVersion

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

where __H: Hasher,

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Gles3MinorVersion

fn eq(&self, other: &Gles3MinorVersion) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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