Versions/Environment

1. rustc 1.84.1 (e71f9a9a9 2025-01-27)
2. Ubuntu 22.04.5 LTS, inside WSL
3. registry+https://github.com/rust-lang/crates.io-index#mongodb@3.2.0

The bug

The crate does not compile without the dns-resolver feature enabled, on version 3.2.0 and version 3.1.1.

Reproduction steps

1. Checkout v3.2.0
2. $ cargo build --no-default-features --features rustls-tls,compat-3-0-0

Alt steps:

1. Create empty crate
2. Add mongodb = { version = "3", default-features = false, features = ["rustls-tls", "compat-3-0-0"] } to Cargo.toml

(Edit: removed solution, since it doesn't actually fix issue)

[the10thWiz]

One minor update - it appears to compile on master.

Additionally, I have confirmed this issue also affects another of my systems.

• OS: Void Linux
• Rust version: rustc 1.81.0 (eeb90cda1 2024-09-04)
• mongodb version: v3.2.0

Thanks for the report! As you've noticed, this is fixed at head, and we'll be releasing 3.2.1 in the near future including this fix.
