Struct Range

Source
pub struct Range { /* private fields */ }
Expand description

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§

Source§

impl Range

Source

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.

Source

pub fn any() -> Range

Source

pub fn upper(&self) -> &Interval

Source

pub fn lower(&self) -> &Interval

Source

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

Source

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

Checks if a version is satisfied by this Range.
