Struct Range 

pub struct Range { /* private fields */ }

An npm version range: ||-separated alternatives, each a (possibly space-separated) set of comparators. Rust’s VersionReq handles only comma-separated comparators and has no ||, yet || ranges are pervasive in published packages’ dependencies (e.g. @lit/reactive-element’s ^1.6.2 || ^2.1.0). A Range parses npm’s grammar into a set of VersionReqs and is satisfied when any alternative is — so transitive resolution works on real-world trees. (version_req stays for the single-comparator-set case.)

Implementations

impl Range

pub fn any() -> Range

A range matching any version (*).

pub fn parse(spec: &str) -> Result<Range, Error>

Parse an npm range. || separates alternatives; within one, npm’s space-separated comparators are joined with commas for semver. A bare full version is an exact pin; */x/empty/latest match anything.

pub fn matches(&self, version: &Version) -> bool

Whether version satisfies any alternative.

Trait Implementations

impl Clone for Range

fn clone(&self) -> Range

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Range

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

Formats the value using the given formatter.

impl Display for Range

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

impl From<VersionReq> for Range

fn from(req: VersionReq) -> Range

Converts to this type from the input type.

impl FromStr for Range

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Range, Error>

Parses a string s to return a value of this type.
