Trait MaterialLayout 

Source 
pub trait MaterialLayout: Send + Sync {
    // Required methods
    fn register_strategy(&mut self, strategy: &dyn ShadingStrategy);
    fn upload(
        &mut self,
        handle: MaterialHandle,
        strategy: &dyn ShadingStrategy,
        values: &[MaterialValue],
    );
}
Expand description

Consumes resolved material values and decides how they are laid out in memory - as a single array-of-structs blob (see the pack::aos module), as per-field structure-of-arrays buffers, or otherwise. ShadingStrategy describes what fields exist and what their values are; MaterialLayout decides where those values live.

Required Methods§

Source

fn register_strategy(&mut self, strategy: &dyn ShadingStrategy)

Prepares this layout to store values for strategy’s fields. Called once per strategy, before any upload for a material using it.

Source

fn upload( &mut self, handle: MaterialHandle, strategy: &dyn ShadingStrategy, values: &[MaterialValue], )

Writes values (as resolved by strategy.resolve(), in strategy.fields() order) into this layout’s storage for handle.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
