Module subxt_core::metadata

A Metadata type, which is used through this crate.

This can be decoded from the bytes handed back from a node when asking for metadata.

Examples

use subxt_core::metadata;

// We need to fetch the bytes from somewhere, and then we can decode them:
let metadata_bytes = include_bytes!("../../../artifacts/polkadot_metadata_small.scale");
let metadata = metadata::decode_from(&metadata_bytes[..]).unwrap();

Structs

• Metadata
  A cheaply clone-able representation of the runtime metadata received from a node.

Traits

• DecodeWithMetadata
  This trait is implemented for all types that also implement scale_decode::DecodeAsType.
• EncodeWithMetadata
  This trait is implemented for all types that also implement scale_encode::EncodeAsType.

Functions

• decode_from
  Attempt to decode some bytes into Metadata, returning an error if decoding fails.
