17//! Runtime APIs for estimating xcm fee payment.
18//! This crate offers two APIs, one for estimating fees,
19//! which can be used for any type of message, and another one
20//! for returning the specific messages used for transfers, a common
21//! feature.
22//! Users of these APIs should call the transfers API and pass the result to the
23//! fees API.
