Cargo.toml has rust-version with the value 1.69.0; however that version does not work as can be seen below:

error: package `rmpv v1.0.1` cannot be built because it requires rustc 1.70 or newer, while the currently active rustc version is 1.69.0
Either upgrade to rustc 1.70 or newer, or use
cargo update -p rmpv@1.0.1 --precise ver
where `ver` is the latest version of `rmpv` supporting rustc 1.69.0

Solution
Since rust-toolchain.toml is already used, change its value to the actual MSRV and drop the use of rust-version altogether.
