New Features

• Add const array bson conversion (#601)

The MongoDB Rust driver team is pleased to announce the v3.0.0 release of the bson crate.

Highlighted Changes

3.0 updates several APIs in backwards-incompatible ways; in most cases these changes should require only minor updates in application code.

Most notably:

• Unified Error Hierarchy: 3.0 adds the bson::error::Error type, with fields for values common across errors like message or associated key and a kind enum that provides granular root cause information.
• &CStr: The bson crate now provides types that directly model the BSON spec "cstring" type, removing a potential source of panic!s and allowing validation at either run-time or compile-time for constant strings.
• Optional serde: Integration with serde is now an optional feature; in support of this, the API has been updated to clarify where methods are for encoding (directly converting Rust BSON values into BSON bytes) or for serialization (converting arbitrary Rust structs to BSON values or bytes via the serde crate).

For detailed information on breaking changes and code examples, please see the migration guide.

The MongoDB Rust driver team is pleased to announce the v2.12.0 release of the bson crate.

Highlighted Changes

This release was largely driven by external contributions!
