Introduction to Rust Error Handling
Core Concepts of Rust Error Handling
// Core Rust concepts
fn main() {
// Type inference
let x = 42;
let name = String::from("Rust");
// Pattern matching
match x {
0 => println!("zero"),
1..=100 => println!("small"),
_ => println!("large"),
}
// Option type
let maybe: Option<i32> = Some(42);
if let Some(val) = maybe {
println!("Got: {}", val);
}
