SemVer comparison operator: =, >, >=, <, <=, ~, ^, *.

Op::Exact

•  =I.J.K — exactly the version I.J.K
•  =I.J — equivalent to >=I.J.0, <I.(J+1).0
•  =I — equivalent to >=I.0.0, <(I+1).0.0

Op::Wildcard

•  I.J.* — equivalent to =I.J
•  I.* or I.*.* — equivalent to =I

Op::Greater

•  >I.J.K
•  >I.J — equivalent to >=I.(J+1).0
•  >I — equivalent to >=(I+1).0.0

Op::GreaterEq

•  >=I.J.K
•  >=I.J — equivalent to >=I.J.0
•  >=I — equivalent to >=I.0.0

Op::Less

•  <I.J.K
•  <I.J — equivalent to <I.J.0
•  <I — equivalent to <I.0.0

Op::LessEq

•  <=I.J.K
•  <=I.J — equivalent to <I.(J+1).0
•  <=I — equivalent to <(I+1).0.0

Op::Tilde (“patch” updates)

Tilde requirements allow the patch part of the semver version (the third number) to increase.

•  ~I.J.K — equivalent to >=I.J.K, <I.(J+1).0
•  ~I.J — equivalent to =I.J
•  ~I — equivalent to =I

Op::Caret (“compatible” updates)

Caret requirements allow parts that are right of the first nonzero part of the semver version to increase.

•  ^I.J.K (for I>0) — equivalent to >=I.J.K, <(I+1).0.0
•  ^0.J.K (for J>0) — equivalent to >=0.J.K, <0.(J+1).0
•  ^0.0.K — equivalent to =0.0.K
•  ^I.J (for I>0 or J>0) — equivalent to ^I.J.0
•  ^0.0 — equivalent to =0.0
•  ^I — equivalent to =I

Trait Implementations

impl Clone for VersionComparator

fn clone(&self) -> VersionComparator

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VersionComparator

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

Formats the value using the given formatter.

impl Default for VersionComparator

fn default() -> VersionComparator

Returns the “default value” for a type.

impl Display for VersionComparator

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

Formats the value using the given formatter.

impl Hash for VersionComparator

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 Into<Op> for VersionComparator

fn into(self) -> Op

Used to register to a management system based on semantic versioning,

impl Ord for VersionComparator

fn cmp(&self, other: &VersionComparator) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for VersionComparator

fn eq(&self, other: &VersionComparator) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for VersionComparator

fn partial_cmp(&self, other: &VersionComparator) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
