Struct Dependency 

pub struct Dependency {
    pub kind: DependencyKind,
    pub from: PackageID,
    pub on: PackageID,
    /* private fields */
}

A relation of dependency between 2 crate::Packages

Fields

kind: DependencyKind

Type of dependency

from: PackageID

ID of the package that defined this dependency

on: PackageID

ID of the package that is being depended on

Implementations

impl Dependency

pub fn svs(&self) -> Option<&SourceVersionSpecifier>

The source and version range chosen by the dependent package.

Example

let svs = dependency.svs().unwrap();
assert_eq!(svs, "^4.2.0");
assert!(svs.is_npm());

pub fn alias_name<'a>(&'a self) -> Option<PackageNameBorrowed<'a>>

If the dependency is from npm, aliasing a package with a different name, this represents the name under which it’s aliased, e.g. if package.json defines the dependency as "lodash": "npm:@chastelock/lodash-fork@^4.0.0", crate::Package::name will be @chastelock/lodash-fork, but crate::Dependency::alias_name will be lodash. (If dependency is not from npm, the behavior is undefined.)

Example

let dependencies = chastefile.package_dependencies(root_pid);
let dependency = dependencies.first().unwrap();
assert_eq!(chastefile.package(dependency.on).name().unwrap(), "@chastelock/lodash-fork");
assert_eq!(dependency.alias_name().unwrap(), "lodash");

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