Struct PypiParser 

pub struct PypiParser;

Parser for Python pyproject.toml files.

Supports both PEP 621 standard format and Poetry format. Uses toml_edit to preserve source positions for LSP operations.

Examples

use deps_pypi::parser::PypiParser;
use tower_lsp_server::ls_types::Uri;

let content = r#"
[project]
dependencies = ["requests>=2.28.0", "flask[async]>=3.0"]
"#;

let parser = PypiParser::new();
let uri = Uri::from_file_path("/test/pyproject.toml").unwrap();
let result = parser.parse_content(content, &uri).unwrap();
assert_eq!(result.dependencies.len(), 2);

Implementations

impl PypiParser

pub const fn new() -> Self

Create a new PyPI parser.

pub fn parse_content(&self, content: &str, uri: &Uri) -> Result<ParseResult>

Parse pyproject.toml content and extract all dependencies.

Parses both PEP 621 and Poetry formats in a single pass.

Errors

Returns an error if:

• TOML is malformed
• PEP 508 dependency specifications are invalid

Examples

let parser = PypiParser::new();
let content = std::fs::read_to_string("pyproject.toml").unwrap();
let uri = Uri::from_file_path("/project/pyproject.toml").unwrap();
let result = parser.parse_content(&content, &uri).unwrap();

Trait Implementations

impl Default for PypiParser

fn default() -> Self

Returns the “default value” for a type.

impl ManifestParser for PypiParser

type Dependency = PypiDependency

Parsed dependency type for this ecosystem.

type ParseResult = ParseResult

Parse result containing dependencies and optional workspace information.

fn parse(&self, content: &str, doc_uri: &Uri) -> Result<Self::ParseResult>

Parses a manifest file and extracts all dependencies with positions.
