Struct Manifest 

pub struct Manifest {
    pub package: PkgInfo,
    pub dependencies: Option<HashMap<PkgName, VersionReq>>,
    pub constraints: Option<Arc<HashMap<PkgName, VersionReq>>>,
    pub sources: Option<Arc<HashMap<PkgName, SrcInfo>>>,
}

A structure of package manifest.

The package manifest contains basic informations about package for example a package name, package description, and package dependencies. These informations can be used to package installation.

Fields

package: PkgInfo

dependencies: Option<HashMap<PkgName, VersionReq>>

Package dependencies.

constraints: Option<Arc<HashMap<PkgName, VersionReq>>>

Package constraints.

sources: Option<Arc<HashMap<PkgName, SrcInfo>>>

Custrom sources.

Implementations

impl Manifest

pub fn new(name: PkgName) -> Self
