Struct PypiDependency 

pub struct PypiDependency {
    pub name: String,
    pub name_range: Range,
    pub version_req: Option<String>,
    pub version_range: Option<Range>,
    pub extras: Vec<String>,
    pub extras_range: Option<Range>,
    pub markers: Option<String>,
    pub markers_range: Option<Range>,
    pub section: PypiDependencySection,
    pub source: PypiDependencySource,
}

Parsed dependency from pyproject.toml with position tracking.

Stores all information about a Python dependency declaration, including its name, version requirement, extras, environment markers, and source positions for LSP operations. Positions are critical for features like hover, completion, and inlay hints.

Examples

use deps_pypi::types::{PypiDependency, PypiDependencySection, PypiDependencySource};
use tower_lsp_server::ls_types::{Position, Range};

let dep = PypiDependency {
    name: "requests".into(),
    name_range: Range::new(Position::new(5, 4), Position::new(5, 12)),
    version_req: Some(">=2.28.0,<3.0".into()),
    version_range: Some(Range::new(Position::new(5, 13), Position::new(5, 27))),
    extras: vec!["security".into()],
    extras_range: None,
    markers: Some("python_version>='3.8'".into()),
    markers_range: None,
    section: PypiDependencySection::Dependencies,
    source: PypiDependencySource::PyPI,
};

assert_eq!(dep.name, "requests");
assert!(matches!(dep.section, PypiDependencySection::Dependencies));

Trait Implementations

impl Clone for PypiDependency

fn clone(&self) -> PypiDependency

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PypiDependency

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Dependency for PypiDependency

fn name(&self) -> &str

Package name

fn name_range(&self) -> Range

LSP range of the dependency name

fn version_requirement(&self) -> Option<&str>

Version requirement string (e.g., “^1.0”, “>=2.0”)

fn version_range(&self) -> Option<Range>

LSP range of the version string

fn source(&self) -> DependencySource

Dependency source (registry, git, path)

fn as_any(&self) -> &(dyn Any + 'static)

Downcast to concrete type

fn features(&self) -> &[String]

Feature flags (ecosystem-specific, empty if not supported)

impl DependencyInfo for PypiDependency

fn name(&self) -> &str

Dependency name (package/crate name).

fn name_range(&self) -> Range

LSP range of the dependency name in the source file.

fn version_requirement(&self) -> Option<&str>

Version requirement string (e.g., “^1.0”, “~2.3.4”).

fn version_range(&self) -> Option<Range>

LSP range of the version string (for inlay hints positioning).

fn source(&self) -> DependencySource

Dependency source (registry, git, path).

fn features(&self) -> &[String]

Feature flags requested (Cargo-specific, empty for npm).

impl PartialEq for PypiDependency

fn eq(&self, other: &PypiDependency) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
