Struct Venv 

pub struct Venv;

Adapter for standard Python venv projects.

Trait Implementations

impl PackageManager for Venv

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

Detect a plain-venv project:

• requirements.txt must exist (otherwise it’s probably not a managed venv project)
• At least one directory with pyvenv.cfg must exist in the repo root
• uv.lock must NOT exist (uv adapter takes priority)

uv’s precedence is also enforced centrally in adapters::detect_adapters, which covers uv projects declared only through [tool.uv] in pyproject.toml.

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

Return all venv directories (any folder containing pyvenv.cfg) as bloat dirs.

fn enforce_lockfile(&self, path: &Path, _policy: EnforcePolicy) -> Result<()>

Pure inspection: reads requirements.txt and runs nothing, so neither half of EnforcePolicy applies.

fn restore(&self, path: &Path) -> Result<()>

Recreate the environment in .venv.

Note: the adapter prunes any directory containing pyvenv.cfg, whatever it is called, but restore always recreates .venv — the original folder name is not recorded anywhere once the directory is gone.

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

Not a lockfile in the strict sense — requirements.txt pins whatever its author pinned — but it is the file this adapter verifies and rebuilds from, which is what the caller wants to be told about.

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

Human-readable name for this adapter (e.g., “npm”, “pnpm”, “uv”).
