Struct PackageIdSpec

pub struct PackageIdSpec {
    name: String,
    version: Option<PartialVersion>,
    url: Option<Url>,
    kind: Option<SourceKind>,
}
Expand description

Some or all of the data required to identify a package:

  1. the package name (a String, required)
  2. the package version (a Version, optional)
  3. the package source (a Url, optional)

If any of the optional fields are omitted, then the package ID may be ambiguous, there may be more than one package/version/url combo that will match. However, often just the name is sufficient to uniquely define a package ID.

Implementations§

§

impl PackageIdSpec

pub fn new(name: String) -> PackageIdSpec

pub fn with_version(self, version: PartialVersion) -> PackageIdSpec

pub fn with_url(self, url: Url) -> PackageIdSpec

pub fn with_kind(self, kind: SourceKind) -> PackageIdSpec

pub fn parse(spec: &str) -> Result<PackageIdSpec, PackageIdSpecError>

Parses a spec string and returns a PackageIdSpec if the string was valid.

§Examples

Some examples of valid strings

use cargo_util_schemas::core::PackageIdSpec;

let specs = vec![
    "foo",
    "foo@1.4",
    "foo@1.4.3",
    "foo:1.2.3",
    "https://github.com/rust-lang/crates.io-index#foo",
    "https://github.com/rust-lang/crates.io-index#foo@1.4.3",
    "ssh://git@github.com/rust-lang/foo.git#foo@1.4.3",
    "file:///path/to/my/project/foo",
    "file:///path/to/my/project/foo#1.1.8"
];
for spec in specs {
    assert!(PackageIdSpec::parse(spec).is_ok());
}
