//! Conversion from rustdoc-types format version 55 to 56
//!
//! Changes in v56:
//! - Added `ItemKind::Attribute` enum variant
//!
//! Strategy: Parse as v55, serialize to JSON, deserialize as v56
//! Since this is just an enum addition, no JSON patching is needed.

use rustdoc_types_56 as v56;

/// Convert a v55 Crate to v56
///
/// This works by round-tripping through sonic_rs::Value.
/// Since v56 only adds a new enum variant that won't exist in v55 data,
/// we only need to update the format_version field.
