Struct JavaVersion 

pub struct JavaVersion {
    pub major: u64,
    pub minor: u64,
    pub patch: u64,
    pub raw: String,
}

Parsed Java version with relaxed extraction of major/minor/patch.

Handles formats like 11.0.2, 1.8.0_202-ea, 17.0.2+13-LTS, 11-ea, and 17.0.8.1 (extra segments are ignored).

The Display implementation renders as {major}.{minor}.{patch}, except when all three are zero — in that case the raw string is shown as a fallback.

Fields

major: u64

Major version number (e.g. 11 in 11.0.2).

For legacy Java 8 this is the second component — 1.8.0_202 becomes major = 8.

minor: u64

Minor version number (e.g. 0 in 11.0.2).

Defaults to 0 when only the major component is specified.

patch: u64

Patch / security-update version number (e.g. 2 in 11.0.2).

Defaults to 0 when only major and minor are specified.

raw: String

The raw version string as produced by java -version.

Preserved for display when automatic parsing falls back to 0.0.0.

Implementations

impl JavaVersion

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

Relaxed parse: strips 1. prefix, splits on non-digits, takes first three numeric parts as major/minor/patch.

Trait Implementations

impl Clone for JavaVersion

fn clone(&self) -> JavaVersion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JavaVersion

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

Formats the value using the given formatter.

impl Display for JavaVersion

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

Formats the value using the given formatter.

impl Eq for JavaVersion

impl Ord for JavaVersion

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 JavaVersion

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

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.
