MSRV
This crate currently has an MSRV of Rust 1.70. Increasing the MSRV is considered a breaking change and thus requires a major version bump.
We cannot make any guarantees about the MSRV of our dependencies. You may be required to pin one of our dependencies to a lower version in your own Cargo.toml in order to compile with the minimum supported Rust version. Eventually Cargo will handle this automatically. See rust-lang/cargo#9930 for more.
