Enum VersionConstraint 

pub enum VersionConstraint {
    Exact(Version),
    Caret(Version),
    Tilde(Version),
    GreaterOrEqual(Version),
    Less(Version),
    Range(Version, Version),
}

Represents a version constraint (e.g., “^1.2.3”, “~1.2.3”, “>=1.2.3”)

Variants

Exact(Version)

Exact version match

Caret(Version)

Caret constraint: ^1.2.3 allows >=1.2.3 and <2.0.0

Tilde(Version)

Tilde constraint: ~1.2.3 allows >=1.2.3 and <1.3.0

GreaterOrEqual(Version)

Greater than or equal

Less(Version)

Less than

Range(Version, Version)

Range constraint: >=1.0.0 <2.0.0

Implementations

impl VersionConstraint

pub fn parse(constraint_str: &str) -> Result<Self>

Parses a version constraint string

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

Checks if a version satisfies this constraint

pub fn constraint_string(&self) -> String

Converts constraint to string

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.
