Struct semver_parser::range::Predicate

pub struct Predicate {
    pub op: Op,
    pub major: u64,
    pub minor: Option<u64>,
    pub patch: Option<u64>,
    pub pre: Vec<Identifier>,
}

Struct representing a version comparison predicate.

Struct contaions operation code and data for comparison of version::Versions.

Examples

Parsing Predicate from string and checking its fields:

use semver_parser::range;

let p = range::parse_predicate(">=1.1")?.expect("non-empty");
assert_eq!(p.op, range::Op::GtEq);
assert_eq!(p.major, 1);
assert_eq!(p.minor.unwrap(), 1);
assert!(p.patch.is_none());
assert!(p.pre.is_empty());

Fields

op: Op

Operation code for this predicate, like "greater than" or "exact match".

major: u64

Major version.

minor: Option<u64>

Optional minor version.

patch: Option<u64>

Optional patch version.

pre: Vec<Identifier>

Collection of Identifiers of version, like "alpha1" in "1.2.3-alpha1".

Trait Implementations

impl PartialEq for Predicate

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

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

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

This method tests for !=.

impl Eq for Predicate

impl Debug for Predicate

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

Formats the value using the given formatter.

impl Clone for Predicate

fn clone(&self) -> Predicate

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Hash for Predicate

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 PartialOrd for Predicate

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

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

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

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

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

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

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

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

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

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

impl Ord for Predicate

fn cmp(&self, other: &Predicate) -> 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.
