Struct Pnpm 

pub struct Pnpm;

PNPM package manager adapter.

Trait Implementations

impl PackageManager for Pnpm

fn name(&self) -> &'static str

Returns the name of the package manager.

fn detect(&self, project_dir: &Path) -> bool

Detects if the project uses pnpm by checking for pnpm-lock.yaml.

fn bloat_dirs(&self, project_dir: &Path) -> Vec<BloatDir>

Returns the bloat directories for pnpm (node_modules).

pnpm does not copy packages into node_modules — it hardlinks them out of its content-addressable store whenever the store and the project sit on the same volume (NTFS included; Windows hardlinks work fine). Deleting such a tree frees only pnpm’s own metadata and any genuinely copied files: the store keeps every linked byte. Counting apparent size here would promise gigabytes and deliver megabytes, so the split is measured per file via the link count.

fn enforce_lockfile( &self, project_dir: &Path, policy: EnforcePolicy, ) -> Result<()>

Enforces the lockfile without installing anything, and without writing.

--lockfile-only resolves package.json and touches no node_modules, but on its own it writes the resolution back to pnpm-lock.yaml. --frozen-lockfile turns that write into a failure, which is the answer we actually want: a lockfile that no longer matches the manifest cannot rebuild the tree we are about to delete, so the prune should be refused rather than the file quietly fixed.

fn restore(&self, project_dir: &Path, timeout: Duration) -> Result<()>

Restores the dependencies using the lockfile.

fn lockfiles(&self) -> &'static [&'static str]

The file this manager rebuilds its bloat directory from.

fn restore_named( &self, project_path: &Path, dir_name: &str, runtime: Option<&str>, timeout: Duration, ) -> Result<()>

PackageManager::restore, told the name the pruned directory had.

fn runtime_tag(&self, project_path: &Path, dir_name: &str) -> Option<String>

The language runtime a bloat directory is built against, recorded at prune time.

fn drift(&self, project_path: &Path) -> Vec<DriftReport>

Installed-but-unrecorded packages, as data instead of a refusal.

fn opt_in(&self) -> bool

Whether this adapter is inert until the user enables it in settings.
