LiteLLM adds a Rust crate for credential redaction in logs, behind LITELLM_RUST
GitHub·low signal
BerriAI/litellm PR #42616, merged 2026-09-23 (+2,131/-247), adds a litellm-logger Rust crate for credential redaction and diagnostic processing, exposed as NativeDiagnosticProcessor through pyo3. With LITELLM_RUST=true, proxy log records go through the Rust processor and fall back to Python on any failure. It is opt-in and in the 1.104.0 dev line, after earlier Rust moves for token counting. The stable v1.102.1 backport shipped the same day with TypeSafe Jev support.
