Enum GlDebugFns 

pub enum GlDebugFns {
    Auto,
    ForceEnabled,
    Disabled,
}

Controls whether OpenGL debug functions are enabled.

Debug functions include glPushDebugGroup, glPopDebugGroup, glObjectLabel, etc. These are useful for debugging but can cause crashes on some buggy drivers.

Variants

Auto

Automatically decide whether to enable debug functions.

Debug functions will be enabled if supported by the driver, unless running on a device known to have buggy debug function implementations (e.g., Mali GPUs which can crash in glPushDebugGroup).

This is the default behavior.

ForceEnabled

Force enable debug functions if supported by the driver.

This ignores any device-specific workarounds and enables debug functions on all devices that support them, including those with known bugs.

Disabled

Disable debug functions entirely.

Debug functions will not be used even if supported by the driver.

Implementations

impl GlDebugFns

pub fn from_env() -> Option<Self>

Choose debug functions setting from the environment variable WGPU_GL_DEBUG_FNS.

Possible values (case insensitive):

• auto - automatically decide based on device
• forceenabled, force_enabled, or enabled - force enable
• disabled - disable entirely

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

pub fn with_env(self) -> Self

Takes the given setting, modifies it based on the WGPU_GL_DEBUG_FNS environment variable, and returns the result.

See from_env for more information.

Trait Implementations

impl Clone for GlDebugFns

fn clone(&self) -> GlDebugFns

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GlDebugFns

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

Formats the value using the given formatter.

impl Default for GlDebugFns

fn default() -> GlDebugFns

Returns the “default value” for a type.

impl PartialEq for GlDebugFns

fn eq(&self, other: &GlDebugFns) -> 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.
