Trait MatchesInstance

Source

pub trait MatchesInstance<Id> {
    // Required method
    fn matches_instance(a: &Asset) -> Result<Id, Error>;
}

Expand description

Unique instances matcher trait.

The Id type should be defined in such a way so that its value can unambigiously identify an instance. I.e., if instances are grouped (e.g., as tokens in an NFT collection), the Id should contain both the group ID and the item group-local ID.

This unified interface allows us to avoid duplicating the XCM adapters for non-grouped and grouped instances.

NOTE: The trait implementors should follow the convention of identifying the collection-less NFTs by an XCM Asset of the form { asset_id: NFT_ID, fun: Fungibility::NonFungible(AssetInstance::Undefined) }.

Required Methods§

fn matches_instance(a: &Asset) -> Result<Id, Error>

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.
