Struct luminance::shader::UniformBuilder

pub struct UniformBuilder<'a, B> where
    B: ?Sized + Shader,  { /* fields omitted */ }

A builder of Uniform.

A UniformBuilder is an important type as it’s the only one that allows to safely create Uniform values.

Parametricity

• B is the backend type. It must implement the Shader trait.

Implementations

impl<'a, B> UniformBuilder<'a, B> where
    B: ?Sized + Shader, 

pub fn ask<T>(&mut self, name: &str) -> Result<Uniform<T>, UniformWarning> where
    B: for<'u> Uniformable<'u, T>, 

Ask the creation of a Uniform, identified by its name.

pub fn ask_or_unbound<T>(&mut self, name: &str) -> Uniform<T> where
    B: for<'u> Uniformable<'u, T>, 

Ask the creation of a Uniform, identified by its name.

If the name is not found, an unbound Uniform is returned (i.e. a Uniform) that does nothing.
