I wish that I could check in a file that would specify various clippy lints for my entire Cargo workspace, and have that be applied to all the crates, libraries, binaries, and examples.
That's not possible with clippy, but it is possible with cranky!
cargo-cranky is just a wrapper around cargo-clippy; it examines your Cranky.toml config file, and constructs the necessary cargo-clippy command line.
For example, if Clippy.toml contains this:
txt
warn = [
"empty_structs_with_brackets",
"cast_possible_truncation",
]
and I run cargo cranky, I get those extra lints:
txt
warning: found empty brackets on struct declaration
--> src/main.rs:11:12
|
11 | struct Unit {}
| ^^^
txt
warning: casting `u64` to `u8` may truncate the value
--> src/main.rs:23:9
|
23 | x as u8
This is exactly the same as manually running cargo clippy with the extra parameters --warn clippy::empty_structs_with_brackets and --warn clippy::cast_possible_truncation.
You may find some useful clippy lints for your project in the clippy documentation. I recommend browsing the "pedantic" and "restriction" groups.
cargo install cargo-cranky
Does it work with vscode?
Yes! Just type cranky into the "Check On Save: Command" setting, or drop this into settings.json:
txt
{
"rust-analyzer.checkOnSave.command": "cranky"
}
