Struct NpmDependency 

pub struct NpmDependency {
    pub name: String,
    pub name_range: Range,
    pub version_req: Option<String>,
    pub version_range: Option<Range>,
    pub section: NpmDependencySection,
}

Parsed dependency from package.json with position tracking.

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

Examples

use deps_npm::types::{NpmDependency, NpmDependencySection};
use tower_lsp_server::ls_types::{Position, Range};

let dep = NpmDependency {
    name: "express".into(),
    name_range: Range::new(Position::new(5, 4), Position::new(5, 13)),
    version_req: Some("^4.18.2".into()),
    version_range: Some(Range::new(Position::new(5, 16), Position::new(5, 25))),
    section: NpmDependencySection::Dependencies,
};

assert_eq!(dep.name, "express");
assert!(matches!(dep.section, NpmDependencySection::Dependencies));

Fields

name: String

Trait Implementations

impl Clone for NpmDependency

fn clone(&self) -> NpmDependency

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NpmDependency

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

Formats the value using the given formatter.

impl Dependency for NpmDependency

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

Downcast to concrete type

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

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

impl DependencyInfo for NpmDependency

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 NpmDependency

fn eq(&self, other: &NpmDependency) -> 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.
