Default: Enabled

Source Code

What it does ​

Checks for manual implementations of expect.

Example ​

cairo
fn main() {
    let foo: Option::<i32> = Option::None;
    let _foo = match foo {
        Option::Some(x) => x,
        Option::None => core::panic_with_felt252('err'),
    };
}

Can be rewritten as:

cairo
fn main() {
    let foo: Option::<i32> = Option::None;
    let _foo = foo.expect('err');
}
