Implementations

impl WriterFlags

pub const ADJUST_COORDINATE_SPACE: WriterFlags = _

Available on wgpu_core only.

Flip output Y and extend Z from (0, 1) to (-1, 1).

pub const TEXTURE_SHADOW_LOD: WriterFlags = _

Available on wgpu_core only.

Supports GL_EXT_texture_shadow_lod on the host, which provides additional functions on shadows and arrays of shadows.

pub const DRAW_PARAMETERS: WriterFlags = _

Available on wgpu_core only.

Supports ARB_shader_draw_parameters on the host, which provides support for gl_BaseInstanceARB, gl_BaseVertexARB, and gl_DrawIDARB.

pub const INCLUDE_UNUSED_ITEMS: WriterFlags = _

Available on wgpu_core only.

Include unused global variables, constants and functions. By default the output will exclude global variables that are not used in the specified entrypoint (including indirect use), all constant declarations, and functions that use excluded global variables.

pub const FORCE_POINT_SIZE: WriterFlags = _

Available on wgpu_core only.

Emit PointSize output builtin to vertex shaders, which is required for drawing with PointList topology.

https://registry.khronos.org/OpenGL/specs/es/3.2/GLSL_ES_Specification_3.20.html#built-in-language-variables The variable gl_PointSize is intended for a shader to write the size of the point to be rasterized. It is measured in pixels. If gl_PointSize is not written to, its value is undefined in subsequent pipe stages.

Available on wgpu_core only.

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
