Required Methods

fn build( &self, params: &MaterialArgs, input_types: &[ValueType], ) -> Result<MaterialBuild, String>

Provided Methods

fn numeric_descriptor( &self, _params: &MaterialArgs, _input_types: &[ValueType], ) -> Result<Option<NumericDescriptor>, String>

Describe an implemented strict numeric contract without allocating evaluator state.

fn params(&self) -> &[ParamSpec]

fn update_trigger( &self, _params: &MaterialArgs, _input_types: &[ValueType], ) -> Result<MaterialUpdateTrigger, String>

Dyn Compatibility

This trait is dyn compatible.

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