Rust Error: Cannot Find Macro 'lazy_static' - Solution

This error message indicates that the Rust compiler cannot locate the 'lazy_static' macro within your program's scope.

To resolve this, you need to add the 'lazy_static' crate to your project's dependencies in the 'Cargo.toml' file:

[dependencies]
lazy_static = '1.4.0'

Subsequently, import the 'lazy_static' crate into your Rust program by including this line at the beginning of your file:

#[macro_use]
extern crate lazy_static;

This action should make the 'lazy_static' macro accessible within your program's scope and eliminate the error.
