pub struct WorkspacePackageRef<'a> { /* private fields */ }

Facade for cargo_metadata ::Package

Implementations

impl<'a> WorkspacePackageRef<'a>

pub fn name(&'a self) -> &'a str

The name field as given in the Cargo.toml

pub fn dependencies( &'a self, ) -> Map<Iter<'a, Dependency>, fn(&'a Dependency) -> DependencyRef<'a>>

List of dependencies of this particular package

pub fn manifest_file(&self) -> Result<ManifestFile, PathError>

Path to the manifest Cargo.toml

pub fn version(&self) -> Version

The version field as specified in the Cargo.toml

pub fn publish(&self) -> Option<&Vec<String>>

List of registries to which this package may be published (derived from the publish field). Publishing is unrestricted if None, and forbidden if the Vec is empty. This is always None if running with a version of Cargo older than 1.39.

pub fn metadata(&self) -> &Value

Contents of the free form package.metadata section. This contents can be serialized to a struct using serde :

use serde ::Deserialize;
use serde_json ::json;

#[ derive( Debug, Deserialize ) ]
struct SomePackageMetadata
{
  some_value: i32,
}

fn main()
{
  let value = json!
  ({
    "some_value" : 42,
});

  let package_metadata: SomePackageMetadata = serde_json ::from_value( value ).unwrap();
  assert_eq!( package_metadata.some_value, 42 );
}

pub fn repository(&self) -> Option<&String>

The repository URL as specified in the Cargo.toml

pub fn features(&self) -> &BTreeMap<String, Vec<String>>

Features provided by the crate, mapped to the features required by that feature.
