rustHow do I get the name of a variable in Rust?

You can get the name of a variable in Rust by using the std::any::type_name function. This function takes a reference to a type and returns a &'static str containing the name of the type.

Example code

let x = 5;
let type_name = std::any::type_name::<&x>();
println!("Type of x is {}", type_name);

Output example

Type of x is i32

Code explanation

• let x = 5;: This declares a variable x with the value 5.
• let type_name = std::any::type_name::<&x>();: This uses the std::any::type_name function to get the type name of the variable x. The <&x> syntax is used to specify the type of the variable.
• println!("Type of x is {}", type_name);: This prints the type name of the variable x to the console.
