Struct SchemaVersion

pub struct SchemaVersion(Version);

The schema version of a type

A SchemaVersion wraps a semver::Version, which means that the tracked version should follow semver. However, for backwards compatibility reasons it is possible to initialize a SchemaVersion using a non-semver compatible string, if it can be parsed to a single u64 (e.g. "1").

Examples

use std::str::FromStr;

use alpm_types::SchemaVersion;

// create SchemaVersion from str
let version_one = SchemaVersion::from_str("1.0.0").unwrap();
let version_also_one = SchemaVersion::from_str("1").unwrap();
assert_eq!(version_one, version_also_one);

// format as String
assert_eq!("1.0.0", format!("{}", version_one));
assert_eq!("1.0.0", format!("{}", version_also_one));

Implementations

impl SchemaVersion

pub fn new(version: SemverVersion) -> Self

Create a new SchemaVersion

pub fn inner(&self) -> &SemverVersion

Return a reference to the inner type

Trait Implementations

impl Clone for SchemaVersion

fn clone(&self) -> SchemaVersion

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SchemaVersion

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

Formats the value using the given formatter.

impl Display for SchemaVersion

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

Formats the value using the given formatter.

impl FromStr for SchemaVersion

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

Create a new SchemaVersion from a string

When providing a non-semver string with only a number (i.e. no minor or patch version), the number is treated as the major version (e.g. "23" -> "23.0.0").

type Err = Error

The associated error which can be returned from parsing.

impl Ord for SchemaVersion

fn cmp(&self, other: &SchemaVersion) -> 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 SchemaVersion

fn eq(&self, other: &SchemaVersion) -> 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 SchemaVersion

fn partial_cmp(&self, other: &SchemaVersion) -> 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.
