Struct luminance::shader::Program

pub struct Program<B: ?Sized, Sem, Out, Uni> where
    B: Shader,  { /* fields omitted */ }

A shader program.

Shader programs are GPU binaries that execute when a draw command is issued.

Parametricity

• B is the backend type.
• Sem is the Semantics type.
• Out is the render target type.
• Uni is the UniformInterface type.

Implementations

impl<B: ?Sized, Sem, Out, Uni> Program<B, Sem, Out, Uni> where
    B: Shader,
    Sem: Semantics, 

pub fn adapt<Q>(
    self
) -> Result<BuiltProgram<B, Sem, Out, Q>, AdaptationFailure<B, Sem, Out, Uni>> where
    Q: UniformInterface<B>, 

Create a new UniformInterface but keep the Program around without rebuilding it.

Parametricity

• Q is the new UniformInterface.

pub fn adapt_env<Q, E>(
    self,
    env: &mut E
) -> Result<BuiltProgram<B, Sem, Out, Q>, AdaptationFailure<B, Sem, Out, Uni>> where
    Q: UniformInterface<B, E>, 

Create a new UniformInterface but keep the Program around without rebuilding it, by using a mutable environment variable.

Parametricity

• Q is the new UniformInterface.
• E is the mutable environment variable.

pub fn readapt_env<E>(
    self,
    env: &mut E
) -> Result<BuiltProgram<B, Sem, Out, Uni>, AdaptationFailure<B, Sem, Out, Uni>> where
    Uni: UniformInterface<B, E>, 

Re-create the UniformInterface but keep the Program around without rebuilding it.

Parametricity

• E is the mutable environment variable.
