[Hyper] is the low-level HTTP implementation for Rust. Hyperx is an extraction of the hyper 0.11 typed header module, with minimized dependencies, for continued use with hyper 0.12 or later, where it was dropped.
MSRV := 1.39.0
The crate will fail fast on any lower rustc (via a build.rs version check) and is also CI tested on this version.
