Trait PackageLoader 

pub trait PackageLoader {
    // Required method
    fn load(&mut self, import: &mut Import) -> Result<Sources, String>;
}

Trait to load packages from various sources.

Required Methods

fn load(&mut self, import: &mut Import) -> Result<Sources, String>

Load a package specified by the import parameter.

Parameters

• import: A mutable reference to an Import structure, which contains:
  • path: The path to the package or directory to be imported.
  • imp_type: The type of import, which can specify a single name, a list of names, or all names in a path.
  • relative: A boolean indicating if the path is relative to the current directory.
  • src: A BoundSource to be updated with the names of the located files.

Behavior

The load method is responsible for locating and loading the requested package(s). The loaded packages are returned as a Sources map, where the key is the package name and the value is its content. Implementers must:

• Track already loaded sources to avoid loading and returning them again.
• Update import.src with the names of the found packages, even if they are not included in the Sources map.

The implementation should handle the following import types:

• Single: Load a specific file by its name.
• List: Load a list of specified files or names from a specific file.
• Glob: Load all files in a directory or all names from a specific file.
