Struct GlBackendOptions 

Source 
pub struct GlBackendOptions {
    pub gles_minor_version: Gles3MinorVersion,
    pub fence_behavior: GlFenceBehavior,
    pub debug_fns: GlDebugFns,
}
Expand description

Configuration for the OpenGL/OpenGLES backend.

Part of BackendOptions.

Fields§

§gles_minor_version: Gles3MinorVersion

Which OpenGL ES 3 minor version to request, if using OpenGL ES.

§fence_behavior: GlFenceBehavior

Behavior of OpenGL fences. Affects how on_completed_work_done and device.poll behave.

§debug_fns: GlDebugFns

Controls whether debug functions (glPushDebugGroup, glPopDebugGroup, glObjectLabel, etc.) are enabled when supported by the driver.

By default (GlDebugFns::Auto), debug functions are automatically disabled on devices with known bugs (e.g., Mali GPUs can crash in glPushDebugGroup). Use GlDebugFns::ForceEnabled to override this behavior, or GlDebugFns::Disabled to disable debug functions entirely.

See also InstanceFlags::DISCARD_HAL_LABELS, which prevents debug markers and labels from being sent to any backend, but without the driver-specific bug workarounds provided here.

Implementations§

Source§

impl GlBackendOptions

Source

pub fn from_env_or_default() -> GlBackendOptions

Choose OpenGL backend options by calling from_env on every field.

See those methods for more information.

Source

pub fn with_env(self) -> GlBackendOptions

Takes the given options, modifies them based on the environment variables, and returns the result.

This is equivalent to calling with_env on every field.
