Version constraint types

Variants

Exact(String)

Exact version match (e.g., “1.2.3”)

Caret(String)

Caret constraint (e.g., “^1.2.3” matches >=1.2.3 <2.0.0)

Tilde(String)

Tilde constraint (e.g., “~1.2.0” matches >=1.2.0 <1.3.0)

GreaterEqual(String)

Greater than or equal (e.g., “>=1.0.0”)

LessEqual(String)

Less than or equal (e.g., “<=2.0.0”)

Range

Range constraint (e.g., “>=1.0.0,<2.0.0”)

Fields

min: Option<String>

max: Option<String>

Any

Any version (no constraint)

Implementations

impl VersionConstraint

pub fn parse(constraint: &str) -> Result<Self, VersionError>

Parse a version constraint string

pub fn satisfies(&self, version: &str) -> Result<bool, VersionError>

Check if a version satisfies this constraint

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.
