Struct Range

pub struct Range { /* private fields */ }

A continguous range in which a version can fall into. Syntax for ranges mirrors that of Pub or Cargo. Ranges can accept caret and tilde syntax, as well as less-than/greater-than specifications (just like Cargo). Like Pub, the any Range is completely unbounded on both sides. Pre-release Versions can satisfy a Range iff the Range mentions a pre-release Version on either bound, or if the Range is unbounded on the upper side. Additionally, if a greater-than and/or less-than Range also has a ! after the inequality symbol, the Range will include pre-release versions. >=! 1.0.0 accepts all pre-releases of 1.0.0, along with the greater versions. <! 2.0.0 includes pre-releases of 2.0.0. >! and > mean the same thing, as do <=! and <=.

Implementations

impl Range

pub fn new(lower: Interval, upper: Interval) -> Option<Range>

Creates a new Range.

All Ranges have to be valid, potentially true constraints. If a nonsensical range is suggested, None is returned.

pub fn any() -> Range

pub fn upper(&self) -> &Interval

pub fn lower(&self) -> &Interval

pub fn take(self) -> (Interval, Interval)

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

Checks if a version is satisfied by this Range.

Trait Implementations

impl Clone for Range

fn clone(&self) -> Range

Returns a copy 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

Formats the value using the given formatter.

impl From<Range> for Constraint

fn from(r: Range) -> Constraint

Converts to this type from the input type.

impl From<Version> for Range

fn from(v: Version) -> 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<Self, Self::Err>

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

impl Hash for Range

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Range

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