Enum Op 

pub enum Op {
    Exact,
    Greater,
    GreaterEq,
    Less,
    LessEq,
    Tilde,
    Caret,
    Wildcard,
}

Versioning comparison operators used in a Requirement: =, >, >=, <, <=, ~, ^, *.

Variants

Exact

A matching Versioning exactly equals the requirement.

Greater

A matching Versioning must be strictly greater than the requirement.

GreaterEq

A matching Versioning must be greater than or equal to the requirement.

Less

A matching Versioning must be strictly less than the requirement.

LessEq

A matching Versioning must be less than or equal to the requirement.

Tilde

A matching Versioning may have a patch (or last component of the) version greater than or equal to the requirement.

Caret

A matching Versioning has its first non-zero component equal to the requirement, and all other components greater than or equal to the requirement.

Wildcard

Any Versioning matches the requirement.

Trait Implementations

impl Clone for Op

fn clone(&self) -> Op

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Op

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

Formats the value using the given formatter.

impl Display for Op

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

Formats the value using the given formatter.

impl Hash for Op

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 Op

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