Armin Ronacher highlights limitations in Rust's Serde serialization library through concrete corner cases, such as arbitrary precision numbers conflicting with internally tagged enums and flattening breaking integer key parsing. While acknowledging Serde's ecosystem dominance, he proposes rethinking serialization design to address these interaction bugs.
Background
Serde is the de facto standard serialization framework for Rust, used by the vast majority of Rust crates. Armin Ronacher is the creator of Flask and a prominent Python developer who has adopted Rust at Sentry.
