## Description Prevent `WeakConnectionHandle` from keeping the allocation for a `ConnectionInner` alive. `ConnectionInner` is quite large, 6048 bytes when I measured it. `Arc` is just an 8 byte pointer. So before the weak handle would keep a large allocation alive. Now it just keeps a tiny allocation alive, consisting of a pointer and 2 refcounts, so 24 bytes on 64 bit machines. The downside of this approach is that every connection access needs to do a double dereference. It's important to keep `WeakConnectionHandle` slim because it is used in downstream APIs by users, who would likely assume that keeping something called a `WeakConnectionHandle` would not force the `ConnectionInner` allocation to stay alive: https://github.com/n0-computer/iroh/issues/3565
Iroh Quinn
This is a fork based on quinn, maintained by n0. Currently published to crates.io under
iroh-quinn.
Main differences to upstream quinn
- Small API improvements
- Implements additional QUIC extensions
- Multipath
- QAD
- QNT
- Expanded support for QLOG
Quinn is a pure-rust, async-compatible implementation of the IETF [QUIC][quic] transport protocol.
- Simultaneous client/server operation
- Ordered and unordered stream reads for improved performance
- Works on stable Rust, tested on Linux, macOS and Windows
- Pluggable cryptography, with a standard implementation backed by [rustls][rustls] and [ring][ring]
- Application-layer datagrams for small, unreliable messages
- Future-based async API
- Minimum supported Rust version of 1.83.0
