Shader data backend.

Required Associated Types

type ShaderDataRepr

Representation of the data by the backend.

Required Methods

unsafe fn new_shader_data(
    &mut self,
    values: impl Iterator<Item = T>
) -> Result<Self::ShaderDataRepr, ShaderDataError>

Build a new shader data from some values represented via an iterator.

unsafe fn get_shader_data_at(
    shader_data: &Self::ShaderDataRepr,
    i: usize
) -> Result<T, ShaderDataError>

Access an item at index i.

unsafe fn set_shader_data_at(
    shader_data: &mut Self::ShaderDataRepr,
    i: usize,
    x: T
) -> Result<T, ShaderDataError>

Set an item at index i.

Return the previous value.

unsafe fn set_shader_data_values(
    shader_data: &mut Self::ShaderDataRepr,
    values: impl Iterator<Item = T>
) -> Result<(), ShaderDataError>

Set values by providing an iterator.
