Hi !

Quick post today to share how to find a variable data type in Rust. As far as I understand, we can use several ways to do this. In example, we can use these 2 std functions:

    use std::any::type_name function
    use std::intrinsics::type_name

The full sample code below create 2 vectors with different data, and print the data type of the vector, and of some of the vector’ elements. This is the output:

   Compiling datatype01 v0.1.0 (C:\src\labs\RustLabs\datatype01)
    Finished dev [unoptimized + debuginfo] target(s) in 0.55s
     Running `target\debug\datatype01.exe`
alloc::vec::Vec<char>
char
i32

Sample Source Code

Happy coding!
