Trait ConstantTypeInfo 

pub trait ConstantTypeInfo {
    type TypeId: Clone;

    // Required method
    fn constant_info(
        &self,
        pallet_name: &str,
        constant_name: &str,
    ) -> Result<ConstantInfo<'_, Self::TypeId>, ConstantInfoError<'_>>;
}

This can be implemented for anything capable of providing Constant information.

Required Associated Types

type TypeId: Clone

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

Required Methods

fn constant_info( &self, pallet_name: &str, constant_name: &str, ) -> Result<ConstantInfo<'_, Self::TypeId>, ConstantInfoError<'_>>

Get information about a constant
