Struct Semver 

pub struct Semver {
    pub major: u64,
    pub minor: u64,
    pub patch: u64,
}

A semantic version: major, minor and patch. A pre-release or build part after - or + is not part of the order.

use riff_core::build::Semver;

let v: Semver = "0.4.1".parse().unwrap();
assert_eq!(v, Semver { major: 0, minor: 4, patch: 1 });
assert_eq!(v.line(), "0.4");
assert_eq!("1.2.0-rc1".parse::<Semver>().unwrap().line(), "1");
assert!("0.4".parse::<Semver>().is_err());
assert!("v0.4.1".parse::<Semver>().is_err());

Fields

major: u64

minor: u64

patch: u64

Implementations

impl Semver

pub fn line(self) -> String

The line as text: 0.4 or 1.

pub fn line_before(self) -> Option<Semver>

The first version of the line before this one. None for the line 0.0, and for the first major: the last minor line of the major 0 is not known.

use riff_core::build::Semver;

let v = |s: &str| s.parse::<Semver>().unwrap();
assert_eq!(v("0.4.2").line_before(), Some(v("0.3.0")));
assert_eq!(v("2.1.0").line_before(), Some(v("1.0.0")));
assert_eq!(v("1.0.0").line_before(), None);
assert_eq!(v("0.0.9").line_before(), None);

pub fn line_after(self) -> Semver

The first version of the line after this one.

use riff_core::build::Semver;

let v = |s: &str| s.parse::<Semver>().unwrap();
assert_eq!(v("0.4.2").line_after(), v("0.5.0"));
assert_eq!(v("1.3.2").line_after(), v("2.0.0"));

pub fn same_line(self, other: Semver) -> bool

True when the two versions are on the same line.

use riff_core::build::Semver;

let v = |s: &str| s.parse::<Semver>().unwrap();
assert!(v("0.4.0").same_line(v("0.4.3")));
assert!(!v("0.4.0").same_line(v("0.5.0")));
assert!(v("1.2.0").same_line(v("1.9.4")));

pub fn riff_lines(self) -> Vec<Semver>

The lines of riff that a riff-server of this version talks with, as the first version of each line: its own line (01M3MX1DYY6AVDW946NR0B9T2C) and the line before (01M3MX1E1EY1M7JGNCN6FCEVQK).

use riff_core::build::Semver;

let v = |s: &str| s.parse::<Semver>().unwrap();
assert_eq!(v("0.4.2").riff_lines(), [v("0.4.0"), v("0.3.0")]);
assert_eq!(v("1.3.0").riff_lines(), [v("1.0.0")]);
assert_eq!(v("4.1.0").riff_lines(), [v("4.0.0"), v("3.0.0")]);

Trait Implementations

impl Clone for Semver

fn clone(&self) -> Semver

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Semver

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

Formats the value using the given formatter.

impl Display for Semver

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

Formats the value using the given formatter.

impl FromStr for Semver

type Err = String

The associated error which can be returned from parsing.

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

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

impl Ord for Semver

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Semver

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

impl PartialOrd for Semver

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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