To run from root of project use: '''code cargo run -p day-01 --bin part1 '''
So -p means package. So the day-01 has da Cargo.toml where the name is specified as "day-01"
To run a test from root of project use: '''code cargo test -p day-01 --bin part1 '''
So -p means package. So the day-01 has da Cargo.toml where the name is specified as "day-01"
To create a new day from the root of the project we initialize a new library '''code cargo new --lib 2023/day-01 '''
When done, you need to just create a new bin folder under the src so you would have src/bin and move the lib.rs to that bin folder. You can then rename the file to part1.rs
Do not forget To be able to run or test the files you need to have the days in
