Trait AssetIdExtractor 

pub trait AssetIdExtractor {
    type AssetId;

    // Required methods
    fn asset_id_from_address(address: &[u8; 20]) -> Result<Self::AssetId, Error>;
    fn asset_index(id: &Self::AssetId) -> Option<u32>;
}

Means of extracting the asset id from the precompile address.

Required Associated Types

type AssetId

Required Methods

fn asset_id_from_address(address: &[u8; 20]) -> Result<Self::AssetId, 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.

Implementors

impl AssetIdExtractor for InlineAssetIdExtractor

type AssetId = u32

impl<Runtime, Instance: 'static> AssetIdExtractor for ForeignAssetIdExtractor<Runtime, Instance>

where Runtime: Config<Instance> + Config<ForeignAssetId = <Runtime as Config<Instance>>::AssetId> + Config,

type AssetId = <Runtime as Config<Instance>>::AssetId
