Enum VersionReq 

pub enum VersionReq {
    Exact(Version),
    AtLeast(Version),
    AtMost(Version),
    Range(Version, Version),
    Caret(Version),
    Tilde(Version),
    Any,
    Compound(Vec<VersionReq>),
}

Version requirement supporting exact, range, caret, and tilde expressions

Variants

Exact(Version)

Exact version

AtLeast(Version)

Minimum version (>=)

AtMost(Version)

Maximum version (<=)

Range(Version, Version)

Range (>= min, < max)

Caret(Version)

Caret range: ^1.2.3 means >=1.2.3, <2.0.0

Tilde(Version)

Tilde range: ~1.2.3 means >=1.2.3, <1.3.0

Any

Any version

Compound(Vec<VersionReq>)

Compound requirement: all sub-requirements must be satisfied

Implementations

impl VersionReq

pub fn parse(s: &str) -> Self

Parse version requirement from string.

Supports:

• * or empty: any version
• 1.2.3: exact version
• >=1.2.3: minimum version
• <=1.2.3: maximum version
• ^1.2.3: compatible with (same major for major > 0)
• ~1.2.3: approximately (same major.minor)
• >=1.2.0, <2.0.0: compound range (comma-separated)

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

Check if version satisfies this requirement

Trait Implementations

impl Clone for VersionReq

fn clone(&self) -> VersionReq

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VersionReq

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

Formats the value using the given formatter.

impl PartialEq for VersionReq

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