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

You can get the type of a variable in Rust using the std::any::type_name function. This function takes a reference to a variable and returns a string containing the type of the variable.

Example code

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

Output example

Type of x is i32

Code explanation

• let x = 5;: This declares a variable x with the value 5.
• let type_of_x = std::any::type_name(&x);: This calls the std::any::type_name function with a reference to the variable x and assigns the returned string to the variable type_of_x.
• println!("Type of x is {}", type_of_x);: This prints the string stored in type_of_x to the console.
