Enum Operator 

pub enum Operator {
    Less,
    LessOrEqual,
    Equal,
    Approximate,
    GreaterOrEqual,
    Greater,
}

Version comparison operator for dependency atoms

Used as a prefix on versioned dependencies to constrain which versions satisfy the dependency.

See PMS 8.3.1.

Variants

Less

< — strictly less than the specified version.

LessOrEqual

<= — less than or equal to the specified version.

Equal

= — exactly the specified version (including revision). When used with a version ending in *, performs prefix matching per PMS 8.3.1 (e.g., =pkg-1.2* matches 1.2.3, 1.2.4, etc.).

Approximate

~ — matches the same base version, ignoring the revision (e.g. ~dev-lang/rust-1.75.0 matches -r0, -r1, etc.).

GreaterOrEqual

>= — greater than or equal to the specified version.

Greater

> — strictly greater than the specified version.

Trait Implementations

impl Clone for Operator

fn clone(&self) -> Operator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Operator

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

Formats the value using the given formatter.

impl Display for Operator

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

Formats the value using the given formatter.

impl Hash for Operator

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 Operator

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