v1.2.0

🎅 Merry Christmas! 🎄

Added

• Add smol_str03 feature (#486)

Changed

• Schemas generated for HashMap/BTreeMap with enum keys are now more specific (#452)

v1.1.0

Added

• Public functions that have no side-effects are now marked with #[must_use] so that they report a lint warning when the returned value is unused, as this likely indicates a mistake.

Fixed

• Improve accuracy of schemas for flattened enums, in particular: unit variants of externally-tagged enums, and enums wrapped in Option<>. (#464 / #483)

v1.0.5

Fixed

• Fix schema.pointer_mut() to resolve URI fragment identifiers like #/$defs/foo, matching current behaviour of schema.pointer() (#478 / #479)

v1.0.4

Fixed

• Fix JsonSchema impl on atomic types being ignored on non-nightly compilers due to a buggy cfg check (#453)
• Fix compatibility with minimal dependency versions, e.g. old(-ish) versions of syn (#450)
• Fix derive for empty tuple variants (#455)

v1.0.3

Fixed

• Fix compile error when a doc comment is set on both a transparent (or newtype) struct and its field (#446)
• Fix json_schema!() macro compatibility when used from pre-2021 rust editions (#447)

v1.0.2

Fixed

• Fix schema properties being incorrectly reordered during serialization (#444)

v1.0.1

Fixed

• Deriving JsonSchema with no_std broken due to std::borrow::ToOwned trait not being in scope (#441)

v1.0.0

This is a major release with many additions, fixes and changes since 0.8 (but not many since 0.9). While the basic usage (deriving JsonSchema and using schema_for!() or SchemaGenerator) is mostly unchanged, you may wish to consult the migration guide which covers some of the most significant changes.

Changes since 1.0.0-rc.2:

Added

• #[schemars(bound = ...)] attributes are now used from fields as well as containers
• The Schema::pointer(...) method now works when given a JSON pointer in URI Fragment representation with a leading # character. In particular, this means that you can now lookup a schema from a $ref value using that method.

Fixed

• Schema names that contain special characters are now correctly encoded when used inside a $ref value (#436)
• Optimise type param usage in SchemaGenerator::subschema_for, reducing LLVM line count and improving compile times (#439)

v1.0.0-rc.2

Added

• Serde attributes that you want schemars to ignore can now be "unset" by including them in a schemars attribute with a ! prefix, e.g. #[schemars(!from)] (#433 / #434)

Removed

• ⚠️ Deprecated items have been removed:
  • SchemaSettings::option_nullable and SchemaSettings::option_add_null_type fields
  • gen module

v1.0.0-rc.1

Added

• Impl JsonSchema for chrono::TimeDelta (#357)
• Support with/into/from/try_from container attributes (#210 / #267)

Changed

• Use oneOf when generating schema for serialized mixed-type sequences (#348) - the previous behaviour was to always use true schema (i.e. any value) for mixed-type sequences
