Enum semver_parser::range::Op

pub enum Op {
    Ex,
    Gt,
    GtEq,
    Lt,
    LtEq,
    Tilde,
    Compatible,
    Wildcard(WildcardVersion),
}

Enum representing operation in Predicate.

This enum represents an operation for comparing two version::Versions.

Examples

Parsing Op from string:

use semver_parser::range;
use std::str::FromStr;

let exact = range::Op::from_str("=")?;
assert_eq!(exact, range::Op::Ex);
let gt_eq = range::Op::from_str(">=")?;
assert_eq!(gt_eq, range::Op::GtEq);

Variants

Ex

Exact, =.

Gt

Greater than, >.

GtEq

Greater than or equal to, >=.

Lt

Less than, <.

LtEq

Less than or equal to, <=.

Tilde

Tilde requirements, like ~1.0.0 - a minimal version with some ability to update.

Compatible

Compatible by definition of semver, indicated by ^.

Wildcard(WildcardVersion)

x.y.*, x.*, *.

Trait Implementations

impl PartialOrd for Op

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

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

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

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

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

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

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

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

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

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

impl Ord for Op

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

impl PartialEq for Op

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

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

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

This method tests for !=.

impl Eq for Op

impl Debug for Op

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

Formats the value using the given formatter.

impl Clone for Op

fn clone(&self) -> Op

Returns a copy of the value.

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

Performs copy-assignment from source.

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,

Feeds a slice of this type into the given [Hasher].

impl FromStr for Op

type Err = String

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Op, String>

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