 - In order to save your precious time, and shorten the process for your PRs to be acknowledged, reviewed, and approved, please add the following jobs to your IDE.
-  * Compile the project: `cargo build --all`
-  * Run the 'Clippy' linter on the project: `cargo clippy --all`
-  * Generate the project documentation: `cargo doc --all`

   - The standard library and all required features (by adding `--all-features` after the job)
   - Without the standard library (by adding `--no-default-features --features=pregenerated` after the job)
