code compiles on my friend's pc but not at mine!

[icy grove]

the name of it is is_none, so I'm pretty concerned that it compiles for them

then something is strange with their code

ah

the option contains a vec

which has that function

seems like your code doesn't handle the option properly

try doing cargo clean and then cargo clippy again?

it is a very good linter that runs on the intermediate rust representation

it gives lots of hints and advice on how to make your code faster and more idiomatic

can you post your code?

sounds like Screen::all doesn't return the same thing for you both

might be a different dependency version

Ah, the latest version of screenshots has Screen::all return an Option<Vec>, but an older version just returns a Vec

I think your friend needs to run cargo update

to get a newer version of the crate

woo

welcome to the concept of reproducible builds haha

that's why you need to copy the Cargo.lock file if you want the exact same experience

An idea in that vein if you aren't already: Clone it from a shared repository,
