Release Notes

mongodb/bson-rust (bson)

v2.12.0

Compare Source

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!

• An optional implementation of Hash and Eq for the Bson family of types
• ObjectId::from_parts, allowing direct construction of an ObjectId from its component values
• Helpers for serializing Option<chrono::DateTime<_>> as Option<bson::DateTime>
• A fix for a panic when parsing specific malformed input data into a Decimal128

We've also added optional (off by default) integration with the serde_path_to_error crate, which
provides paths to the precise point of failure for deserialization of nested data structures.
