[BUG] rust - lazy_static crate version is out of date

Created by: AsadMGradex

Generated a server using 'rust-server' generator.

I got this error:

error: use of deprecated item 'std::sync::ONCE_INIT': the new function is now preferred lazy_static! { //-snip-
} ^

cargo.toml: lazy_static = "0.2"

Changing this to: lazy_static = "1.4.0" (most recent version of this crate) will solve this issue
