Build failed while installing

Hi, completely new to Rust, never even written it, just wanted to try out this tool so I installed it but the build failed with the following error

   Compiling zoneinfo_compiled v0.4.8
error[E0599]: no method named `copied` found for type `std::option::Option<&u8>` in the current scope
   --> /home/palash25/.cargo/registry/src/github.com-1ecc6299db9ec823/zoneinfo_compiled-0.4.8/src/lib.rs:131:49

Wanted to know if someone else has faced this issue before and ways to solve this.

Can you update your Rust? You can use rustup to get an up to date version. The cargo version you have ist pretty old so I'm sure your rustc version probably also is.

Keep in mind that if you only want to use this but not compile it, you can always just download the precompiled binary or use the web version. Compiling it is only necessary if you plan on developing it. Of course it'd be great if you contributed something. If you decide to do so and need help, I can mentor you a bit.
