Struct PypiLockParser 

pub struct PypiLockParser;

PyPI lock file parser.

Implements lock file parsing for Python package managers (Poetry, uv). Supports both poetry.lock and uv.lock formats.

Lock File Location

The parser searches for lock files in the following order:

1. poetry.lock in the same directory as pyproject.toml
2. uv.lock in the same directory as pyproject.toml

Poetry takes priority because it’s more established.

Examples

use deps_pypi::lockfile::PypiLockParser;
use deps_core::lockfile::LockFileProvider;
use tower_lsp_server::ls_types::Uri;

let parser = PypiLockParser;
let manifest_uri = Uri::from_file_path("/path/to/pyproject.toml").unwrap();

if let Some(lockfile_path) = parser.locate_lockfile(&manifest_uri) {
    let resolved = parser.parse_lockfile(&lockfile_path).await?;
    println!("Found {} resolved packages", resolved.len());
}

Trait Implementations

impl LockFileProvider for PypiLockParser

fn locate_lockfile(&self, manifest_uri: &Uri) -> Option<PathBuf>

Locates the lock file for a given manifest URI.

fn parse_lockfile<'life0, 'life1, 'async_trait>( &'life0 self, lockfile_path: &'life1 Path, ) -> Pin<Box<dyn Future<Output = Result<ResolvedPackages>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Parses a lock file and extracts resolved packages.

fn is_lockfile_stale( &self, lockfile_path: &Path, last_modified: SystemTime, ) -> bool

Checks if lock file has been modified since last parse.
