serde_with v1.6.3

Changed

• Bump macro crate dependency (serde_with_macros) to 1.4.0 to pull in those improvements.

serde_with_macros v1.4.0

Changed

• Improve error messages when #[serde_as(..)] is misused as a field attribute.
  Thanks to @Lehona for reporting the bug in #233.

• Internal cleanup for assembling and parsing attributes during serde_as processing.

• Change processing on #[serde_as(...)] attributes on fields.

  The attributes will no longer be stripped during proc-macro processing.
  Instead, a private derive macro is applied to the struct/enum which captures them and makes them inert, thus allowing compilation.

  This should have no effect on the generated code and on the runtime behavior.
  It eases integration of third-party crates with serde_with, since they can now process the #[serde_as(...)] field attributes reliably.
  Before this was impossible for derive macros and lead to akward ordering constraints on the attribute macros.

  Thanks to @Lehona for reporting this problem and to @dtolnay for suggesting the dummy derive macro.

serde_with v1.6.2

Added

• New function serde_with::rust::deserialize_ignore_any.
  This function allows deserializing any data and returns the default value of the type.
  This can be used in conjunction with #[serde(other)] to allow deserialization of unknown data carrying enum variants.

  Thanks to @lovasoa for suggesting and implementing it.

serde_with v1.6.1

Added

• Add new types similar to DurationSeconds and TimestampSeconds but for base units of milliseconds, microseconds, and nanoseconds.
  The *WithFrac variants also exist.
• Add SerializeAs implementation for references.

Changed

• Release Sized trait bound from As, Same, SerializeAs, and SerializeAsWrap.
  Only the serialize part is relaxed.
