Struct glutin::context::ContextAttributesBuilder

pub struct ContextAttributesBuilder { /* private fields */ }

The builder to help customizing context

Implementations

impl ContextAttributesBuilder

pub fn new() -> Self

Create new builder.

pub fn with_debug(self, debug: bool) -> Self

Sets the debug flag for the OpenGL context.

Debug contexts are usually slower, but give better error reporting.

The default value for this flag is false.

pub fn with_sharing(self, context: &impl AsRawContext) -> Self

Share the display lists with the given context.

To get sharing working it’s recommended to use the same Config when creating contexts that are going to be shared.

Platform-specific

On Wayland both contexts must use the same Wayland connection.

pub fn with_robustness(self, robustness: Robustness) -> Self

Sets the robustness of the OpenGL context. See the docs of Robustness.

The default is Robustness::NotRobust, because this is what typically expected when you create an OpenGL context. However for safety you should consider Robustness::RobustLoseContextOnReset.

pub fn with_release_behavior(self, release_behavior: ReleaseBehavior) -> Self

The behavior when changing the current context. See the docs of ReleaseBehavior.

The default is ReleaseBehavior::Flush.

pub fn with_profile(self, profile: GlProfile) -> Self

Set the desired OpenGL context profile. See the docs of GlProfile.

By default the profile is unspecified.

Api-specific

macOS: - not supported, the latest is picked automatically.

pub fn with_context_api(self, api: ContextApi) -> Self

Set the desired OpenGL context api. See the docs of ContextApi.

By default the supported api will be picked.

pub fn build( self, raw_window_handle: Option<RawWindowHandle> ) -> ContextAttributes

Build the context attributes.

The raw_window_handle isn’t required and here for WGL compatibility.

Api-specific

WGL: - you must pass raw_window_handle for if you plan to use it with window.

Trait Implementations
