Trait CustomValueTypeInfo 

pub trait CustomValueTypeInfo {
    type TypeId: Clone;

    // Required methods
    fn custom_value_info(
        &self,
        name: &str,
    ) -> Result<CustomValueInfo<'_, Self::TypeId>, CustomValueInfoError>;
    fn custom_values(&self) -> impl Iterator<Item = CustomValue<'_>>;
}

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

fn custom_values(&self) -> impl Iterator<Item = CustomValue<'_>>

Iterate over all of the available Custom Values.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
