Trait subxt::metadata::DecodeWithMetadata

pub trait DecodeWithMetadata {
    type Target;

    fn decode_with_metadata(
        bytes: &mut &[u8],
        type_id: u32,
        metadata: &Metadata
    ) -> Result<Self::Target, Error>;

    fn decode_storage_with_metadata(
        bytes: &mut &[u8],
        pallet_name: &str,
        storage_entry: &str,
        metadata: &Metadata
    ) -> Result<Self::Target, Error> { ... }
}

This trait is implemented for types which can be decoded with the help of metadata.

Required Associated Types

type Target

The type that we’ll get back from decoding.

Required Methods

fn decode_with_metadata(
    bytes: &mut &[u8],
    type_id: u32,
    metadata: &Metadata
) -> Result<Self::Target, Error>

Given some metadata and a type ID, attempt to SCALE decode the provided bytes into Self.

Provided Methods

fn decode_storage_with_metadata(
    bytes: &mut &[u8],
    pallet_name: &str,
    storage_entry: &str,
    metadata: &Metadata
) -> Result<Self::Target, Error>

Decode a storage item using metadata. By default, this uses the metadata to work out the type ID to use, but for static items we can short circuit this lookup.
