Enum VersionConstraint 

pub enum VersionConstraint {
    Exact(SemVer),
    Compatible(SemVer),
    AtLeast(SemVer),
    AtMost(SemVer),
    Range {
        min: SemVer,
        max: SemVer,
    },
}

A version constraint that can be evaluated against a concrete SemVer.

Variants

Exact(SemVer)

Exact match — only the specified version satisfies the constraint.

Compatible(SemVer)

Compatible (^) — same major, version >= specified.

AtLeast(SemVer)

At least (>=) — version >= specified (any major).

AtMost(SemVer)

At most (<=) — version <= specified.

Range

Inclusive range — min <= version <= max.

Fields

min: SemVer

max: SemVer

Implementations

impl VersionConstraint

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

Test whether version satisfies this constraint.

pub fn intersect(&self, other: &VersionConstraint) -> Option<VersionConstraint>

Attempt to compute the intersection of two constraints.

Returns None if the constraints cannot be combined into a single Range (e.g. two Exact constraints with different versions).

Trait Implementations

impl Clone for VersionConstraint

fn clone(&self) -> VersionConstraint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VersionConstraint

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

Formats the value using the given formatter.

impl PartialEq for VersionConstraint

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