Trait StorageTypeInfo 

pub trait StorageTypeInfo {
    type TypeId: Clone;

    // Required methods
    fn storage_info(
        &self,
        pallet_name: &str,
        storage_entry: &str,
    ) -> Result<StorageInfo<'_, Self::TypeId>, StorageInfoError<'_>>;
    fn storage_entries(&self) -> impl Iterator<Item = Entry<'_>>;

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

This is implemented for all metadatas exposed from frame_metadata and is responsible for extracting the type IDs and related info needed to decode storage entries.

Required Associated Types

type TypeId: Clone

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

Required Methods

fn storage_info( &self, pallet_name: &str, storage_entry: &str, ) -> Result<StorageInfo<'_, Self::TypeId>, StorageInfoError<'_>>

Get the information needed to decode a specific storage entry key/value.

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

Iterate over all of the available storage entries.

Provided Methods

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

Iterate over all of the available storage entries in a given pallet.

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.
