Expand description

Trait for computing XCM fees and managing asset pricing. This allows pallets to delegate fee calculation to an external system (e.g., pallet-xcm-weight-trader) instead of maintaining their own storage.

Required Methods§

Source

fn compute_fee( weight: Weight, asset_location: &Location, ) -> Result<u128, DispatchError>

Compute the fee amount for a given weight and asset location.

The fee should be calculated based on the weight and asset pricing configured for the given asset location.

Source

fn get_asset_price(asset_location: &Location) -> Option<u128>

Get the current price/fee-per-second for an asset, if configured. Returns None if the asset is not configured.

Source

fn set_asset_price( _asset_location: Location, _value: u128, ) -> Result<(), DispatchError>

Set the price/configuration for an asset.

Source

fn remove_asset(_asset_location: Location) -> Result<(), DispatchError>

Remove the price/configuration for an asset.

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.
