Replace &T to impl AsRef<T>.

auto_ref

Attributes for replace reference parameter &T to impl AsRef<T> or impl Borrow<T>

Usage

use auto_ref::{auto_ref, auto_borrow};

#[auto_ref]
fn example1(s: &str, t: &mut str) {
    println!("{}, {}", s, t);
}

#[auto_borrow]
fn example2(s: &str, t: &mut str) {
    println!("{}, {}", s, t);
}

#[auto_ref(s)]
#[auto_borrow(t)]
fn example3(s: &str, t: &str, u: &str) {
    println!("{}, {}, {}", s, t, u);
}

The above code is convert to

fn example1(s: impl ::core::convert::AsRef<str>, mut t: impl ::core::convert::AsMut<str>) {
    let s: &str = s.as_ref();
    let t: &mut str = t.as_mut();
    println!("{}, {}", s, t);
}

fn example2(s: impl ::core::borrow::Borrow<str>, mut t: impl ::core::borrow::BorrowMut<str>) {
    let s: &str = s.borrow();
    let t: &mut str = t.borrow_mut();
    println!("{}, {}", s, t);
}

fn example3(s: impl ::core::convert::AsRef<str>, t: impl ::core::borrow::Borrow<str>, u: &str) {
    let t: &str = t.borrow();
    let s: &str = s.as_ref();
    println!("{}, {}, {}", s, t, u);
}
