Auto-complete your functions to use ? expressions and return anyhow::Result with less boilerplate!

For convenience, anyhoo reexports anyhow as anyhoo::anyhow:

[dependencies]
anyhoo = { git = "https://github.com/tranzystorek-io/anyhoo", features = ["reexport"] }

You can opt out of this feature if you're using a particular version of anyhow.

A function that reads a line and parses it to an integer.

Default rusty idiom:

fn parse_line() -> anyhow::Result<i32> {
    let mut input = String::new();
    std::io::stdin().read_line(&mut input)?;

    let result = input.parse();
    Ok(result)
}

With anyhoo:

#[anyhoo::anyhoo]
fn parse_line() -> i32 {
    let mut input = String::new();
    std::io::stdin().read_line(&mut input)?;

    input.parse()?
}
