Trait RuntimeApiTypeInfo 

pub trait RuntimeApiTypeInfo {
    type TypeId: Clone;

    // Required methods
    fn runtime_api_info(
        &self,
        trait_name: &str,
        method_name: &str,
    ) -> Result<RuntimeApiInfo<'_, Self::TypeId>, RuntimeApiInfoError<'_>>;
    fn runtime_apis(&self) -> impl Iterator<Item = Entry<'_>>;

    // Provided method
    fn runtime_apis_in_trait(
        &self,
        trait_name: &str,
    ) -> impl Iterator<Item = Cow<'_, str>> { ... }
}

This can be implemented for anything capable of providing Runtime API type information. It is implemented for newer versions of frame-metadata (V15 and above).

Required Associated Types

type TypeId: Clone

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

Required Methods

fn runtime_api_info( &self, trait_name: &str, method_name: &str, ) -> Result<RuntimeApiInfo<'_, Self::TypeId>, RuntimeApiInfoError<'_>>

Get the information needed to encode/decode a specific Runtime API call

fn runtime_apis(&self) -> impl Iterator<Item = Entry<'_>>

Iterate over all of the available Runtime APIs.

Provided Methods

fn runtime_apis_in_trait( &self, trait_name: &str, ) -> impl Iterator<Item = Cow<'_, str>>

Iterate over all of the available Runtime APIs in a given trait.

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.
