Trait staging_xcm_builder::AssetChecking
source · pub trait AssetChecking<AssetId> {
// Required method
fn asset_checking(asset: &AssetId) -> Option<MintLocation>;
}Expand description
Simple trait to indicate whether an asset is subject to having its teleportation into and out of
this chain recorded and if so in what MintLocation.
The overall purpose of asset-checking is to ensure either no more assets are teleported into a
chain than the outstanding balance of assets which were previously teleported out (as in the
case of locally-minted assets); or that no more assets are teleported out of a chain than the
outstanding balance of assets which have previously been teleported in (as in the case of chains
where the asset is not minted locally).
Required Methods§
sourcefn asset_checking(asset: &AssetId) -> Option<MintLocation>
fn asset_checking(asset: &AssetId) -> Option<MintLocation>
Return the teleportation asset-checking policy for the given asset. None implies no
checking. Otherwise the policy detailed by the inner MintLocation should be respected by
teleportation.
