Version constraint types

Variants

Exact(Version)

Exact version match (==)

GreaterThan(Version)

Greater than (>)

GreaterThanOrEqual(Version)

Greater than or equal (>=)

LessThan(Version)

Less than (<)

LessThanOrEqual(Version)

Less than or equal (<=)

Compatible(Version)

Compatible version (~=)

Range(Version, Version)

Range constraint (>=min, <max)

Multiple(Vec<VersionConstraint>)

Multiple constraints (AND logic)

Alternative(Vec<VersionConstraint>)

Alternative constraints (OR logic)

Exclude(Vec<Version>)

Exclude specific versions

Wildcard(String)

Wildcard pattern (e.g., “1.2.*”)

Prefix(Version)

Prefix match: version starts with the given prefix tokens. Used for rez “point release” syntax: pkg-3.11 matches 3.11, 3.11.0, 3.11.5, etc.

Any

Any version

Implementations

impl VersionConstraint

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

Check if a version satisfies this constraint.

Rez semantics: when comparing against a constraint version with fewer tokens, the comparison is done at the depth of the constraint. e.g., >=3 on 3.11.0 → compare first token: 3 >= 3 ✓ <4 on 3.11.0 → compare first token: 3 < 4 ✓

pub fn cmp_at_depth(version: &Version, constraint_ver: &Version) -> Ordering

Compare version against constraint_ver at the depth of constraint_ver.

Rez semantics: constraints with fewer tokens are compared only at the token depth of the constraint.

pub fn and(self, other: VersionConstraint) -> VersionConstraint

Combine two constraints with AND logic

pub fn or(self, other: VersionConstraint) -> VersionConstraint

Combine two constraints with OR logic

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<'de> Deserialize<'de> for VersionConstraint

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for VersionConstraint

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

Formats the value using the given formatter.

impl Hash for VersionConstraint

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.

impl Serialize for VersionConstraint

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for VersionConstraint
