Struct JavaSpec 

pub struct JavaSpec {
    pub vendor: Option<String>,
    pub version: Option<VersionReq>,
    pub arch: Option<String>,
    pub raw: String,
}

A parsed Java installation query spec.

Fields

vendor: Option<String>

Vendor substring to match (case-insensitive).

version: Option<VersionReq>

Version requirement.

arch: Option<String>

Architecture substring to match (case-insensitive).

raw: String

The raw input string.

Implementations

impl JavaSpec

pub fn parse(input: &str) -> Result<Self, String>

Parse a human-readable Java spec string.

Format

<vendor> v<constraint> a<arch>

Both v and a prefixes and their values are optional.

Examples

use java_manager::JavaSpec;

let spec = JavaSpec::parse("Eclipse Adoptium v^17.0.0 ax86_64").unwrap();
assert_eq!(spec.vendor.as_deref(), Some("Eclipse Adoptium"));
assert!(spec.version.is_some());
assert_eq!(spec.arch.as_deref(), Some("x86_64"));

pub fn matches(&self, info: &JavaInfo) -> bool

Check whether a [JavaInfo] matches this spec.

All present criteria (vendor, version, architecture) must match. Missing criteria are ignored (i.e., a spec with no vendor matches any vendor).

Vendor matching is case-insensitive substring. Architecture matching is case-insensitive substring.

Trait Implementations

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

Performs copy-assignment from source.

impl Debug for JavaSpec

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