Input when creating a program.

Variants

SourceCode

Use GLSL source code.

Fields

vertex_shader: &'a str

Source code of the vertex shader.

tessellation_control_shader: Option<&'a str>

Source code of the optional tessellation control shader.

tessellation_evaluation_shader: Option<&'a str>

Source code of the optional tessellation evaluation shader.

geometry_shader: Option<&'a str>

Source code of the optional geometry shader.

fragment_shader: &'a str

Source code of the fragment shader.

transform_feedback_varyings: Option<(Vec<String>, TransformFeedbackMode)>

The list of variables and mode to use for transform feedback.

The information specified here will be passed to the OpenGL linker. If you pass None, then you won’t be able to use transform feedback.

outputs_srgb: bool

Whether the fragment shader outputs colors in sRGB or RGB. This is true by default, meaning that the program is responsible for outputting correct sRGB values.

If this is false, then GL_FRAMEBUFFER_SRGB will be enabled when this program is used (if it is supported).

uses_point_size: bool

Whether the shader uses point size.

Binary

Use a precompiled binary.

Fields

data: Binary

The data.

outputs_srgb: bool

See ProgramCreationInput::SourceCode::outputs_srgb.

uses_point_size: bool

Whether the shader uses point size.

SpirV(SpirvProgram<'a>)

Use a SPIR-V binary.

Trait Implementations

impl<'a> From<Binary> for ProgramCreationInput<'a>

fn from(binary: Binary) -> ProgramCreationInput<'a>

Converts to this type from the input type.

impl<'a> From<SourceCode<'a>> for ProgramCreationInput<'a>

fn from(code: SourceCode<'a>) -> ProgramCreationInput<'a>

Converts to this type from the input type.
