- Bump versions of several dependencies in Cargo.toml for improved functionality and security, including:
- socket2 to 0.6
- nix to 0.31
- toml to 1.0
- x509-parser to 0.18
- dashmap to 6.1
- rand to 0.10
- reqwest to 0.13
- notify to 8.2
- ipnetwork to 0.21
- webpki-roots to 1.0
- criterion to 0.8
- Introduce `OnceLock` for secure random number generation in multiple modules to ensure thread safety and reduce overhead.
- Refactor random number generation calls to use the new `RngExt` trait methods for consistency and clarity.
- Add new PNG files for architectural documentation.
- Remove unused imports across multiple modules
- Add #![allow(dead_code)] for public API items preserved for future use
- Add #![allow(deprecated)] for rand::Rng::gen_range usage
- Add #![allow(unused_assignments)] in main.rs
- Add #![allow(unreachable_code)] in network/stun.rs
- Prefix unused variables with underscore (_ip_tracker, _prefer_ipv6)
- Fix unused_must_use warning in tls_front/cache.rs
This ensures clean compilation without warnings while preserving
public API items that may be used in the future.
When IPv6 is unavailable on the host, treat NetworkUnreachable at
connect() as Ok(None) instead of propagating an error, so the dual
STUN probe succeeds with just the IPv4 result and no spurious WARN.
