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<Arc<dyn PackageInfo>>

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.

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_mapped( &self, mapped_content: HashMap<String, Vec<u8>>, ) -> LoadingResult<Arc<dyn PackageInfo>>

Loads the given mapped package content.

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>
