Struct PreRelease 

pub struct PreRelease(/* private fields */);

A parsed pre-release identifier list such as alpha.1.

Implementations

impl PreRelease

pub fn new(s: &str) -> Result<Self, SemverError>

Parse a pre-release identifier list such as alpha.1.

Examples

use js_semver::PreRelease;

let pre = PreRelease::new("alpha.1").unwrap();

assert_eq!(pre.to_string(), "alpha.1");

Errors

Returns SemverError if s is not valid pre-release metadata.

pub fn is_empty(&self) -> bool

Returns true when there are no pre-release identifiers.

Examples

use js_semver::PreRelease;

assert!(PreRelease::default().is_empty());
assert!(!PreRelease::new("rc.1").unwrap().is_empty());

Trait Implementations

impl Clone for PreRelease

fn clone(&self) -> PreRelease

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PreRelease

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

Formats the value using the given formatter.

impl Default for PreRelease

fn default() -> PreRelease

Returns the “default value” for a type.

impl Display for PreRelease

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

Formats the value using the given formatter.

impl Eq for PreRelease

impl FromStr for PreRelease

type Err = SemverError

The associated error which can be returned from parsing.

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

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

impl Ord for PreRelease

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

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for PreRelease

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for PreRelease

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