Struct bevy_retrograde::core::luminance::shader::ProgramBuilder

pub struct ProgramBuilder<'a, C, Sem, Out, Uni> { /* fields omitted */ }

A Program builder.

This type allows to create shader programs without having to worry too much about the highly generic API.

Implementations

impl<'a, C, Sem, Out, Uni> ProgramBuilder<'a, C, Sem, Out, Uni> where
    C: GraphicsContext,
    Sem: Semantics,
    <C as GraphicsContext>::Backend: Shader, 

pub fn new(ctx: &'a mut C) -> ProgramBuilder<'a, C, Sem, Out, Uni>

Create a new ProgramBuilder from a GraphicsContext.

pub fn from_stages_env<'b, T, G, E>(
    &mut self,
    vertex: &'b Stage<<C as GraphicsContext>::Backend>,
    tess: T,
    geometry: G,
    fragment: &'b Stage<<C as GraphicsContext>::Backend>,
    env: &mut E
) -> Result<BuiltProgram<<C as GraphicsContext>::Backend, Sem, Out, Uni>, ProgramError> where
    T: Into<Option<TessellationStages<'b, Stage<<C as GraphicsContext>::Backend>>>>,
    G: Into<Option<&'b Stage<<C as GraphicsContext>::Backend>>>,
    Uni: UniformInterface<<C as GraphicsContext>::Backend, E>, 

Create a Program by linking Stages and accessing a mutable environment variable.

Parametricity

• T is an Option containing a TessellationStages with Stage inside.
• G is an Option containing a Stage inside (geometry shader).
• E is the mutable environment variable.

Notes

Feel free to look at the documentation of GraphicsContext::new_shader_program for a simpler interface.

    fragment: &'b Stage<<C as GraphicsContext>::Backend>
) -> Result<BuiltProgram<<C as GraphicsContext>::Backend, Sem, Out, Uni>, ProgramError> where
    T: Into<Option<TessellationStages<'b, Stage<<C as GraphicsContext>::Backend>>>>,
    G: Into<Option<&'b Stage<<C as GraphicsContext>::Backend>>>,
    Uni: UniformInterface<<C as GraphicsContext>::Backend, ()>, 

Create a Program by linking Stages.

Parametricity

• T is an Option containing a TessellationStages with Stage inside.
• G is an Option containing a Stage inside (geometry shader).

pub fn from_strings_env<'b, T, G, E>(
    &mut self,
    vertex: &'b str,
    tess: T,
    geometry: G,
    fragment: &'b str,
    env: &mut E
) -> Result<BuiltProgram<<C as GraphicsContext>::Backend, Sem, Out, Uni>, ProgramError> where
    T: Into<Option<TessellationStages<'b, str>>>,
    G: Into<Option<&'b str>>,
    Uni: UniformInterface<<C as GraphicsContext>::Backend, E>, 

Create a Program by linking &strs and accessing a mutable environment variable.

Parametricity

• C is the graphics context.
• T is an Option containing a TessellationStages with &str inside.
• G is an Option containing a Stage inside (geometry shader).
• E is the mutable environment variable.
