Enum Spec 

pub enum Spec {
    Registry(String),
    Alias {
        name: String,
        spec: Box<Spec>,
    },
    Git {
        source: String,
        committish: Option<String>,
    },
    Tarball(String),
    Path(String),
}

A classified npm dependency specifier.

Variants

Registry(String)

A registry spec — an exact version, a semver range, or a dist-tag (e.g. latest) — held raw. Resolve it with version_req (the Rust semver subset of npm’s grammar).

Alias

An npm:<name>@<spec> alias — install name (per the inner spec) under the dependency’s own key.

Fields

name: String

spec: Box<Spec>

Git

A git source — a full git URL or a host:owner/repo / bare owner/repo shorthand — with an optional #<committish> (branch, tag, commit, or semver:<range>).

Fields

source: String

committish: Option<String>

Tarball(String)

A remote tarball fetched over http(s).

Path(String)

A local path (file:…, ./, ../, /abs, ~/…), linked or copied in place.

Implementations

impl Spec

pub fn parse(spec: &str) -> Spec

Classify a dependencies value by form. Never fails — an unparseable-but-registry range is still Spec::Registry; turning it into a VersionReq is a later step.

pub fn is_registry(&self) -> bool

Whether this spec resolves to a registry tarball (the only form npm-utils fetches).

Trait Implementations

impl Clone for Spec

fn clone(&self) -> Spec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Spec

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

Formats the value using the given formatter.

impl Eq for Spec

impl PartialEq for Spec

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