One of the checks failed Rustlings Tests / dev-check (pull_request)
It told me to run command cargo run -- dev update
but this failed should i open an issue or should i just update this file manually ?
windows 11 rustup 1.27.1 cargo 1.79.0 Error message:
cargo run -- dev update
Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.18s
Running `target\debug\rustlings.exe dev update`
Error: Failed to update the file `dev/Cargo.toml`
Caused by:
Failed to find the start of the `bin` list (`bin = [`)
error: process didn't exit successfully: `target\debug\rustlings.exe dev update` (exit code: 1)
I can take care of the CI test later. Probably a Windows issue.
We shouldn't use traits / trait bounds because the exercises about them are after the generics exercises.
How about a function taking &[Option<T>]
and returning Vec<T>
containing only the Some
values?
I changed stringify
to this:
fn into_dispose_nulls<T>(list: Vec<Option<T>>) -> Vec<T> {
list.into_iter().flatten().collect()
}
i tried to have &[Option<T>]
as an argument but it requires T
to implement Clone
(and i couldn't find any suitable workaround)

Oh, yeah. We would need to return something like Vec<&T>
otherwise. But this is fine how you did it with Vec
as argument.
Created a new pull request based on the previous one (#1470).
Added a new generic exercise that focuses on function reusability using generics.
