How to safely and idiomatically convert numeric types in Rust?

Hi! I recently started learning Rust and encountered a problem with number conversion. In other languages (C++, Python) I just wrote `(int)float_var` or `int(float_var)` and it worked. But in Rust the compiler constantly complains. Here's an example of code I'm trying to write: ```rust fn main() { let a: u8 = 10; let b: u16 = 20; let sum = a + b; // Error: cannot add `u16` to `u8` let pi: f64 = 3.14159; let int_pi: u32 = pi; // Error: expected `u32`, found `f64` let x: i32 = 100; let y: u32 = x; // Error: expected `u32`, found `i32` } ``` I understand that Rust is strongly typed, but how do I properly perform such conversions? I've heard about `as`, but it behaves dangerously on overflow. Are there safe and idiomatic ways? I need
