Implementations

impl ExerciseCollection

pub fn new(exercises_dir: PathBuf) -> Result<Self, Error>

pub fn n_opened(&self) -> Result<usize, Error>

pub fn opened(&self) -> Result<BTreeSet<OpenedExercise>, Error>

Return an iterator over all the workshop-runner that have been opened.

pub fn next(&mut self) -> Result<Option<ExerciseDefinition>, Error>

Return the next exercise that should be opened, if we are going through the workshop-runner in the expected order.

pub fn mark_as_solved(&self, exercise: &ExerciseDefinition) -> Result<(), Error>

Record in the database that an exercise was solved, so that it can be skipped next time.

pub fn mark_as_unsolved( &self, exercise: &ExerciseDefinition, ) -> Result<(), Error>

Record in the database that an exercise was not solved, so that it won’t be skipped next time.

pub fn open(&mut self, exercise: &ExerciseDefinition) -> Result<(), Error>

Open a specific exercise.

pub fn close(&mut self, exercise: &ExerciseDefinition) -> Result<(), Error>

Close a specific exercise.

pub fn open_next(&mut self) -> Result<ExerciseDefinition, Error>

Open the next exercise, assuming we are going through the workshop-runner in order.

pub fn exercises_dir(&self) -> &Path

The directory containing all the workshop chapters and workshop-runner.

pub fn iter(&self) -> impl Iterator<Item = &ExerciseDefinition>

Iterate over the workshop-runner in the collection, in the order we expect them to be completed. It returns both opened and unopened workshop-runner.
