Trait CustomValueTypeInfo 

pub trait CustomValueTypeInfo {
    type TypeId: Clone;

    // Required method
    fn custom_value_info(
        &self,
        name: &str,
    ) -> Result<CustomValueInfo<'_, Self::TypeId>, CustomValueInfoError>;
}

This can be implemented for anything capable of providing Custom Value information.

Required Associated Types

type TypeId: Clone

The type of type IDs that we are using to obtain type information.

Required Methods

fn custom_value_info( &self, name: &str, ) -> Result<CustomValueInfo<'_, Self::TypeId>, CustomValueInfoError>

Get information about a constant
