A lockfile handler that keeps track of the dependencies and their current state.

Implementations

impl Lockfile

pub fn new(project_root: &Path) -> Self

project_root is the absolute path to the project root.

You will need to call Lockfile::read to load the lockfile.

pub fn read(&mut self) -> Result<()>

Loads the lockfile from the project root.

Throws an error if the lockfile does not exist.

pub fn get(&self, path: &Path) -> Option<&DepIdentifier>

Get the DepIdentifier for a submodule at a given path.

pub fn len(&self) -> usize

Returns the num of dependencies in the lockfile.

pub fn is_empty(&self) -> bool

Returns whether the lockfile is empty.

pub fn iter(&self) -> impl Iterator<Item = (&PathBuf, &DepIdentifier)>

Returns an iterator over the lockfile.

pub fn exists(&self) -> bool
