) -> Self
[src]
installed_path: P,
pkgdepends: PackageDepends
) -> Self
Opens a database from the specified path.
pub fn is_pkg_installed(&self, pkg_name: &str) -> bool
[src]
Checks if a package is installed
pub fn get_pkg_depends(
&self,
pkg_name: &str
) -> Result<Vec<String>, DatabaseError>
[src]
&self,
pkg_name: &str
) -> Result<Vec<String>, DatabaseError>
Retrieves the dependencies of a package that are listed in its manifest file.
pub fn calculate_depends(
&self,
pkg_name: &str,

) -> Result<(), DatabaseError>
[src]
&self,
pkg_name: &str,
ordered_dependencies: &mut OrderMap<String, ()>
) -> Result<(), DatabaseError>
