Multiple Trait Bounds with the + Operator

Snippet

Multiple Trait Bounds with the + Operator

Trait bounds can be combined using + to require a type implement multiple traits. This allows functions to use functionality from several traits simultaneously, providing flexibility in generic constraints.

snippet.rs
rust
use std::fmt::{Debug, Display};
 
fn print_debug<T>(item: &T)
where
    T: Debug + Display,
{
    println!("Debug: {:?}, Display: {}", item, item);
}
 
fn main() {
    let num = 42;
    print_debug(&num);
}

Breakdown

T: Debug + Display,

Type T must implement both Debug AND Display traits

println!("Debug: {:?}, Display: {}", item, item);

Can call both Debug formatting and Display formatting on item
