v0.6.0 - 2024-08-07

Breaking

Added

  • Support for optional package defmt which allows for easy conversion for error types when using tools like probe-rs for logging over debuggers.
  • Implement Serializer::collect_str
  • Derive Serialize for de::Error and ser::Error

Changed

v0.5.1 - 2023-07-26

Added

  • Support for serializing tuple structs. These are serialized as JSON arrays, which matches serde_json behaviour.
  • Serializer and Deserializer are now pub.
  • Added pub Serializer::end() and Deserializer::end().

Changed

  • Increase MSRV to 1.56.0 to work around dependency-MSRV issues (see #72)

v0.5.0 - 2022-11-04

Changed

  • Changed serialization of f32/f64 that are !is_finite() (i.e. NAN, INFINITY, NEG_INFINITY) to result in JSON null. This matches serde_json behavior.
  • Changed deserialization of JSON null where f32/f64 is expected to result in the respective NAN.
  • [breaking-change] increase MSRV to Rust 1.55.0 due to maybe_uninit_extra.

Added

  • Support for opting out of heapless integration

  • [breaking-change] Heapless dependency updated to 0.6.1

v0.2.0 - 2020-12-11

Added

  • Support for serialization into slices
  • Support for serializing and deserializing unit types, newtypes and variants

Changed

  • Changed deserializations to return the number of bytes used
  • Changed deserializer and serializer to handle escaped strings
  • Changed deserializer to handle whitespaces before sequence
  • Raised MSRV to 1.40.0 in order to use non_exhaustive
