first 10 minutes learning rust, i'm given 58 lint options , i'm thinking: gcc has solution this. something go in .toml file? workaround? gcc’s -werror becomes rustc --deny warnings or crate attribute #![deny(warnings)] . -wall or -weverything aren’t necessary in rust; of sorts of things covered compilation errors or lints default deny or warn. should understand lints that: lints . matters @ least slightly, , very, subjective. lints allow default should so—they’re useful tools specific purposes, enabling lot of them doesn’t make sense. (the box-pointers lint, example: in type of library may wish able “i guarantee uses no heap memory”, it’s not that’s bad .)
