Struct semver::Comparator

pub struct Comparator {
    pub op: Op,
    pub major: u64,
    pub minor: Option<u64>,
    pub patch: Option<u64>,
    pub pre: Prerelease,
}

A pair of comparison operator and partial version, such as >=1.2. Forms one piece of a VersionReq.

Fields

op: Op

major: u64

minor: Option<u64>

patch: Option<u64>

Patch is only allowed if minor is Some.

pre: Prerelease

Non-empty pre-release is only allowed if patch is Some.

Implementations

impl Comparator

pub fn parse(text: &str) -> Result<Self, Error>

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

Trait Implementations

impl Clone for Comparator

fn clone(&self) -> Comparator

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Comparator

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

Formats the value using the given formatter.

impl Display for Comparator

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

Formats the value using the given formatter.

impl FromIterator<Comparator> for VersionReq

fn from_iter<I>(iter: I) -> Self

where I: IntoIterator<Item = Comparator>,

Creates a value from an iterator.

impl FromStr for Comparator

type Err = Error

The associated error which can be returned from parsing.

fn from_str(text: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Comparator

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 Comparator

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