Struct Program 

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

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, 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.
