Struct Loader

pub struct Loader { /* private fields */ }

Manages loading of Mélodium packages.

The loader take care of managing package dependencies, loading inner elements of packages, and building a coherent Collection.

Loading can be made through the load-ing functions, and then final collection rendered using build().

This loader aims to be lazy, please read carefully the behavior of each load-ing function in order to make best use of them.

Implementations

impl Loader

pub fn new(config: LoadingConfig) -> Self

pub fn load_package( &self, requirement: &PackageRequirement, ) -> LoadingResult<()>

Loads the given package, according to requirements.

This function does not load any package content on its own, see Self::load, Self::load_all or the functions of LoaderTrait to get elements required loaded.

pub fn load_raw( &self, raw_content: Arc<Vec<u8>>, ) -> LoadingResult<Arc<dyn PackageInfo>>

Loads the given raw package content.

Returns the name of the package and its main entry point, if any.

This function does not load any package content on its own, see Self::load, Self::load_all or the functions of LoaderTrait to get elements required loaded.

pub fn load( &self, identifier_requirement: &IdentifierRequirement, ) -> LoadingResult<Identifier>

Load the given identifier.

pub fn load_all(&self) -> LoadingResult<()>

Load all the elements from all the packages.

Packages concerned have to be already loaded through Self::load_package of Self::load_raw functions.

pub fn build(&self) -> LoadingResult<Arc<Collection>>

Proceed to build of coherent collection.

pub fn packages(&self) -> Vec<Arc<dyn PackageInfo>>

pub fn collection(&self) -> RwLockReadGuard<'_, Collection>

pub fn get_with_load( &self, identifier_requirement: &IdentifierRequirement, ) -> LoadingResult<Entry>
