Struct reproto_semver::range::Range

pub struct Range {
    pub predicates: Vec<Predicate>,
}

A Range is a struct containing a list of predicates that can apply to ranges of version numbers. Matching operations can then be done with the Range against a particular version to see if it satisfies some or all of the constraints.

Fields

predicates: Vec<Predicate>

Methods

impl Range

fn any() -> Range

any() is a factory method which creates a Range with no constraints. In other words, any version will match against it.

Examples

use reproto_semver::Range;

let anything = Range::any();

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

parse() is the main constructor of a Range. It takes a string like "^1.2.3" and turns it into a Range that matches that particular constraint.

A Result is returned which contains a Error if there was a problem parsing the Range.

Examples

use reproto_semver::Range;

let version = Range::parse("=1.2.3");
let version = Range::parse(">1.2.3");
let version = Range::parse("<1.2.3");
let version = Range::parse("~1.2.3");
let version = Range::parse("^1.2.3");
let version = Range::parse("1.2.3"); // synonym for ^1.2.3
let version = Range::parse("<=1.2.3");
let version = Range::parse(">=1.2.3");

This example demonstrates error handling, and will panic.

use reproto_semver::Range;

let version = match Range::parse("not a version") {
    Ok(version) => version,
    Err(e) => panic!("There was a problem parsing: {}", e),
}

fn exact(version: &Version) -> Range

exact() is a factory method which creates a Range with one exact constraint.

Examples

use reproto_semver::Range;
use reproto_semver::Version;

let version = Version { major: 1, minor: 1, patch: 1, pre: vec![], build: vec![] };
let exact = Range::exact(&version);

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

matches() matches a given Version against this Range.

Examples

use reproto_semver::Range;
use reproto_semver::Version;

let version = Version { major: 1, minor: 1, patch: 1, pre: vec![], build: vec![] };
let exact = Range::exact(&version);

assert!(exact.matches(&version));

fn matches_any(&self) -> bool

Check if range matches any.
