Description
Given the following code: https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=d6dfe3d605639255444883813f8376db
enum CargoMessage {
CompilerArtifact {
filenames: Vec<String>,
target: CargoTarget,
extra: bool,
}
}
struct CargoTarget {
crate_types: Vec<String>,
}
pub fn run_cargo() {
let is_debug_info = |_| true;
let is_dylib = |_| true;
let is_check = true;
let ok = stream_cargo(vec![], &mut |msg| {
let (filenames, crate_types) = match msg {
CargoMessage::CompilerArtifact {
filenames,
target: CargoTarget { crate_types },
..
} => (filenames, crate_types),
_ => return,
};
for filename in filenames {
// Skip files like executables
if !(filename.ends_with(".rlib")
|| filename.ends_with(".lib")
|| filename.ends_with(".a")
|| is_debug_info(&filename)
|| is_dylib(&filename)
|| (is_check && filename.ends_with(".rmeta")))
{
continue;
}
}
});
}
pub fn stream_cargo(
cb: &mut dyn FnMut(CargoMessage),
) -> bool {
true
}The current output is:

Ideally the output should look like:

Printing the entire body of the closure is ... a bit much 😆
