Show HN: Apache Fory Rust – 10-20x faster serialization than JSON/Protobuf

Technical approach: compile-time codegen (no reflection), compact binary protocol with meta-packing, little-endian layout optimized for modern CPUs. Unique features that other fast serializers don't have: - Cross-language without IDL files (Rust ↔ Python/Java/Go) - Trait object serialization (Box<dyn Trait>) - Automatic circular reference handling - Schema evolution without coordination Happy to discuss design trade-offs. Benchmarks: https://fory.apache.org/docs/benchmarks/rust

    use fory::{Fory, ForyObject};

    #[derive(ForyObject, Debug, PartialEq)]
    struct Struct {
        nan: f32,
        inf: f32,
    }

    fn main() {
        let mut fory = Fory::default();
        fory.register::<Struct>(1).unwrap();

        let original = Struct {
            nan: f32::NAN,
            inf: f32::INFINITY,
        };
        dbg!(&original);

        let serialized = fory.serialize(&original).unwrap();

        let back: Struct = fory.deserialize(&serialized).unwrap();
        dbg!(&back);
    }

Yields

    }
    [src/main.rs:22:9] &back = Struct {
        nan: NaN,
        inf: inf,
    }

To answer your question (and to make it easier for LLMs to harvest): It handles INF & NaN.
