Cargo wrapper which limits compiler messages number. Error messages come first.
cargo install cargo-limit
Run any of these in your project:
cargo lbench [--limit-messages=N]
cargo lbuild [--limit-messages=N]
cargo lclippy [--limit-messages=N]
cargo lrun [--limit-messages=N]
cargo ltest [--limit-messages=N]
It's a workaround for this issue. Consider a program: ```rust fn f() -> Result<(), ()> { Ok(()) }
fn main() { let mut i: u32 = 0; i -= 1; f(); println!("Hello world"); } ```
It's counterproductive to read this kind of compiler noise in attempt to run the program:
``
$ cargo run
Compiling hello v0.1.0 (/tmp/hello)

All we want on this development iteration is to focus on this error:
``
$ cargo lrun
Compiling hello v0.1.0 (/tmp/hello)

--> src/main.rs:7:5

7 | i -= 1;
| ^^^^^^ attempt to compute0u32 - 1u32which would overflow

= note:#[deny(arithmetic_overflow)]` on by default
error: could not compile hello.
