DXR: declarative XML-RPC (shared traits, types, and implementations)

The dxr project provides crates for writing XML-RPC API clients and servers in Rust.

This crate contains definitions of all data types, type conversion functionality, and (de)serialization implementations that are needed for dealing with XML-RPC values of all kinds.

All public items are re-exported from the dxr crate, so this crate should be considered an internal implementation detail, and never be imported or used directly.
