Struct nannou::ui::backend::glium::glium::backend::glutin::glutin::ContextBuilder [−]
pub struct ContextBuilder<'a> { pub gl_attr: GlAttributes<&'a Context>, // some fields omitted }
Object that allows you to build Context
s.
Fields
gl_attr: GlAttributes<&'a Context>
The attributes to use to create the context.
Methods
impl<'a> ContextBuilder<'a>
impl<'a> ContextBuilder<'a>
pub fn new() -> ContextBuilder<'a>
pub fn new() -> ContextBuilder<'a>
Initializes a new ContextBuilder
with default values.
pub fn with_gl(self, request: GlRequest) -> ContextBuilder<'a>
pub fn with_gl(self, request: GlRequest) -> ContextBuilder<'a>
Sets how the backend should choose the OpenGL API and version.
pub fn with_gl_profile(self, profile: GlProfile) -> ContextBuilder<'a>
pub fn with_gl_profile(self, profile: GlProfile) -> ContextBuilder<'a>
Sets the desired OpenGL context profile.
pub fn with_gl_debug_flag(self, flag: bool) -> ContextBuilder<'a>
pub fn with_gl_debug_flag(self, flag: bool) -> ContextBuilder<'a>
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) -> ContextBuilder<'a>
pub fn with_gl_robustness(self, robustness: Robustness) -> ContextBuilder<'a>
Sets the robustness of the OpenGL context. See the docs of Robustness
.
pub fn with_vsync(self, vsync: bool) -> ContextBuilder<'a>
pub fn with_vsync(self, vsync: bool) -> ContextBuilder<'a>
Requests that the window has vsync enabled.
By default, vsync is not enabled.
Share the display lists with the given Context
.
pub fn with_multisampling(self, samples: u16) -> ContextBuilder<'a>
pub fn with_multisampling(self, samples: u16) -> ContextBuilder<'a>
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) -> ContextBuilder<'a>
pub fn with_depth_buffer(self, bits: u8) -> ContextBuilder<'a>
Sets the number of bits in the depth buffer.
pub fn with_stencil_buffer(self, bits: u8) -> ContextBuilder<'a>
pub fn with_stencil_buffer(self, bits: u8) -> ContextBuilder<'a>
Sets the number of bits in the stencil buffer.
pub fn with_pixel_format(
self,
color_bits: u8,
alpha_bits: u8
) -> ContextBuilder<'a>
pub fn with_pixel_format(
self,
color_bits: u8,
alpha_bits: u8
) -> ContextBuilder<'a>
Sets the number of bits in the color buffer.
pub fn with_stereoscopy(self) -> ContextBuilder<'a>
pub fn with_stereoscopy(self) -> ContextBuilder<'a>
Request the backend to be stereoscopic.
pub fn with_srgb(self, srgb_enabled: bool) -> ContextBuilder<'a>
pub fn with_srgb(self, srgb_enabled: bool) -> ContextBuilder<'a>
Sets whether sRGB should be enabled on the window.
The default value is false
.
pub fn with_double_buffer(
self,
double_buffer: Option<bool>
) -> ContextBuilder<'a>
pub fn with_double_buffer(
self,
double_buffer: Option<bool>
) -> ContextBuilder<'a>
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>
) -> ContextBuilder<'a>
pub fn with_hardware_acceleration(
self,
acceleration: Option<bool>
) -> ContextBuilder<'a>
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
