s.
Fields§
§gl_attr: GlAttributes<&'a Context>
The attributes to use to create the context.
Implementations§
source§impl<'a> ContextBuilder<'a>
impl<'a> ContextBuilder<'a>
sourcepub fn with_gl(self, request: GlRequest) -> Self
pub fn with_gl(self, request: GlRequest) -> Self
Sets how the backend should choose the OpenGL API and version.
sourcepub fn with_gl_profile(self, profile: GlProfile) -> Self
pub fn with_gl_profile(self, profile: GlProfile) -> Self
Sets the desired OpenGL context profile.
sourcepub fn with_gl_debug_flag(self, flag: bool) -> Self
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
.
sourcepub fn with_gl_robustness(self, robustness: Robustness) -> Self
pub fn with_gl_robustness(self, robustness: Robustness) -> Self
Sets the robustness of the OpenGL context. See the docs of Robustness
.
sourcepub fn with_vsync(self, vsync: bool) -> Self
pub fn with_vsync(self, vsync: bool) -> Self
Requests that the window has vsync enabled.
By default, vsync is not enabled.
Share the display lists with the given Context
.
sourcepub fn with_multisampling(self, samples: u16) -> Self
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.
sourcepub fn with_depth_buffer(self, bits: u8) -> Self
pub fn with_depth_buffer(self, bits: u8) -> Self
Sets the number of bits in the depth buffer.
sourcepub fn with_stencil_buffer(self, bits: u8) -> Self
pub fn with_stencil_buffer(self, bits: u8) -> Self
Sets the number of bits in the stencil buffer.
sourcepub fn with_pixel_format(self, color_bits: u8, alpha_bits: u8) -> Self
pub fn with_pixel_format(self, color_bits: u8, alpha_bits: u8) -> Self
Sets the number of bits in the color buffer.
sourcepub fn with_stereoscopy(self) -> Self
pub fn with_stereoscopy(self) -> Self
Request the backend to be stereoscopic.
sourcepub fn with_srgb(self, srgb_enabled: bool) -> Self
pub fn with_srgb(self, srgb_enabled: bool) -> Self
Sets whether sRGB should be enabled on the window.
The default value is false
.
sourcepub fn with_double_buffer(self, double_buffer: Option<bool>) -> Self
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
sourcepub fn with_hardware_acceleration(self, acceleration: Option<bool>) -> Self
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
