android-abx 0.2.0

//! `serde_root` — deserialize an ABX document's root element straight into
//! a struct with a single call, for files where the whole document *is*
//! one record (as opposed to a wrapper element containing many repeated
//! records — see `serde_pkgs` for that shape instead).
//!
//! Usage:
//!   cargo run --features serialize --example serde_root -- <input.abx>
//!
//! No parser to construct, and — like `quick_xml::de::from_str`/
//! `serde_json::from_slice` — no need to know or declare the root
//! element's tag name; deserialization is structural (attributes, child
//! elements, text), not name-based. Adapt the `Pkg` struct below to
//! whatever your root element actually carries.
