Struct GlBackendOptions

pub struct GlBackendOptions {
    pub gles_minor_version: Gles3MinorVersion,
    pub short_circuit_fences: GlFenceBehavior,
}

Configuration for the OpenGL/OpenGLES backend.

Fields

gles_minor_version: Gles3MinorVersion

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

short_circuit_fences: GlFenceBehavior

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

Implementations

impl GlBackendOptions

pub fn from_env_or_default() -> GlBackendOptions

Choose OpenGL backend options by calling from_env on every field.

See those methods for more information.

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.
