Struct glutin::ContextBuilder

pub struct ContextBuilder<'a> {
    pub gl_attr: GlAttributes<&'a Context>,
    // some fields omitted
}

Object that allows you to build Contexts.

Fields

gl_attr: GlAttributes<&'a Context>

The attributes to use to create the context.

Methods

impl<'a> ContextBuilder<'a>

pub fn new() -> Self

Initializes a new ContextBuilder with default values.

pub fn with_gl(self, request: GlRequest) -> Self

Sets how the backend should choose the OpenGL API and version.

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

Sets the desired OpenGL context profile.

pub fn with_gl_debug_flag(self, flag: bool) -> Self

Sets the debug flag for the OpenGL context.

The default value for this flag is cfg!(debug_assertions), which means that it's enabled when you run cargo build and disabled when you run cargo build --release.

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

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

pub fn with_vsync(self, vsync: bool) -> Self

Requests that the window has vsync enabled.

By default, vsync is not enabled.

pub fn with_shared_lists(self, other: &'a Context) -> Self

Share the display lists with the given Context.

pub fn with_multisampling(self, samples: u16) -> Self

Sets the multisampling level to request. A value of 0 indicates that multisampling must not be enabled.

Panic

Will panic if samples is not a power of two.

pub fn with_depth_buffer(self, bits: u8) -> Self

Sets the number of bits in the depth buffer.

pub fn with_stencil_buffer(self, bits: u8) -> Self

Sets the number of bits in the stencil buffer.

pub fn with_pixel_format(self, color_bits: u8, alpha_bits: u8) -> Self

Sets the number of bits in the color buffer.

pub fn with_stereoscopy(self) -> Self

Request the backend to be stereoscopic.

pub fn with_srgb(self, srgb_enabled: bool) -> Self

Sets whether sRGB should be enabled on the window.

The default value is false.

pub fn with_double_buffer(self, double_buffer: Option<bool>) -> Self

Sets whether double buffering should be enabled.

The default value is None.

Platform-specific

This option will be taken into account on the following platforms:

• MacOS
• Linux using GLX with X
• Windows using WGL

pub fn with_hardware_acceleration(self, acceleration: Option<bool>) -> Self

Sets whether hardware acceleration is required.

The default value is Some(true)

Platform-specific

This option will be taken into account on the following platforms:

• MacOS
• Linux using EGL with either X or Wayland
• Windows using EGL or WGL
• Android using EGL
