# if-to-let-chain

Converts usages of the `if_chain` macro from the

[if-chain crate](https://docs.rs/if_chain/) to `let-chains`.

Example input:

```Rust

if_chain! {

    if let Ok(num) = u16::from_str(s);

    if num < 4000;

    if let Some(e) = v.get(num);

    then {

        println!("{e}");

    }

}

```

Output:

```Rust

if let Ok(num) = u16::from_str(s)

    && num < 4000

    && let Some(e) = v.get(num)

{

    println!("{e}");

}

```

Usage:

```

if-to-let-chain [Options] PATH...

Options:

    -d, --deindent N    number of chars to deindent by (default 4)

    -v, --verbose       print extra information

    -h, --help          print this help

```
