Struct Version 

pub struct Version { /* private fields */ }

A parsed RPM version: [epoch:]version[-release].

Wraps librpm’s opaque rpmver handle. Owns the underlying allocation and frees it on drop.

Implementations

impl Version

pub fn parse(evr: &str) -> Option<Self>

Parse an [epoch:]version[-release] string.

Returns None if the string is not a valid EVR.

Panics

Panics if evr contains an interior NUL byte.

pub fn new( epoch: Option<&str>, version: &str, release: Option<&str>, ) -> Option<Self>

Construct a version from individual components.

epoch and release are optional. Returns None if the inputs are invalid.

Panics

Panics if any argument contains an interior NUL byte.

pub fn epoch(&self) -> Option<&str>

Epoch string (e.g. "1"), or None if no epoch was specified.

pub fn version(&self) -> &str

Version string (e.g. "2.3.4").

pub fn release(&self) -> Option<&str>

Release string (e.g. "5.el9"), or None if no release was specified.

pub fn evr(&self) -> String

Formatted [E:]V[-R] string.

Trait Implementations

impl Debug for Version

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

Formats the value using the given formatter.

impl Display for Version

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

Formats the value using the given formatter.

impl Drop for Version

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

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

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl Eq for Version

impl Ord for Version

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.

impl PartialEq for Version

fn eq(&self, other: &Self) -> 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 Version

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.
