Context

Describe the background behind the problem.
The Rust driver, and Rust as an ecosystem, handles errors very differently than PyMongo. Stack traces are considered a debugging feature, not a normal part of exception handling. Exception handling in general is frowned upon in Rust: the preferred pattern is to treat errors as either recoverable and return them as a value, or unrecoverable and terminate the process. All of these differences pose challenges for a Python driver that wraps Rust.

Definition of done

What must be done to consider the task complete?
Provide possible solutions to each of the following categories:

• Error handling
• OpenTelemetry
• Logging
• APM

Pitfalls

What should the implementer watch out for? What are the risks?

• All behavior must be configurable through Python. Users cannot interface with Rust at all.
• Parity (or near-parity) with PyMongo is expected.
