Release Notes

GREsau/schemars (schemars)

### [`v0.8.16`](https://togithub.com/GREsau/schemars/blob/HEAD/CHANGELOG.md#0816---2023-11-11) [Compare Source](https://togithub.com/GREsau/schemars/compare/v0.8.15...v0.8.16) ##### Fixed: - Reduce size of MIR output (and improve release-mode compile time) when deriving `JsonSchema` ### [`v0.8.15`](https://togithub.com/GREsau/schemars/blob/HEAD/CHANGELOG.md#0815---2023-09-17) [Compare Source](https://togithub.com/GREsau/schemars/compare/v0.8.14...v0.8.15) ##### Added: - Implement `JsonSchema` for `BigDecimal` from `bigdecimal` 0.4 ([https://github.com/GREsau/schemars/pull/237](https://togithub.com/GREsau/schemars/pull/237)) ### [`v0.8.14`](https://togithub.com/GREsau/schemars/blob/HEAD/CHANGELOG.md#0814---2023-09-17) [Compare Source](https://togithub.com/GREsau/schemars/compare/v0.8.13...v0.8.14) ##### Added: - Add `#[schemars(inner(...)]` attribute to specify schema for array items ([https://github.com/GREsau/schemars/pull/234](https://togithub.com/GREsau/schemars/pull/234)) ##### Changed: - New optional associated function on `JsonSchema` trait: `schema_id()`, which is similar to `schema_name()`, but does not have to be human-readable, and defaults to the type name including module path. This allows schemars to differentiate between types with the same name in different modules/crates ([https://github.com/GREsau/schemars/issues/62](https://togithub.com/GREsau/schemars/issues/62) / [https://github.com/GREsau/schemars/pull/247](https://togithub.com/GREsau/schemars/pull/247)) ##### Fixed: - Schemas for `rust_decimal::Decimal` and `bigdecimal::BigDecimal` now match how those types are serialized by default, i.e. as numeric strings ([https://github.com/GREsau/schemars/pull/248](https://togithub.com/GREsau/schemars/pull/248))
