Release Notes

jonasbb/serde_with (serde_with)

v3.1.0: serde_with v3.1.0

Compare Source

Added

• Add FromIntoRef and TryFromIntoRef (#​618)
  Thanks to @​oblique for submitting the PR.

  The new types are similar to the existing FromInto and TryFromInto types.
  They behave different during serialization, allowing the removal of the Clone bound on their SerializeAs trait implementation

Changed

• Improve documentation about cfg-gating serde_as (#​607)
• Bump MSRV to 1.61 because that is required by the crate cfg_eval.
