Expand description

Represents a location that packages can be loaded from. For example, you could load packages from the filesystem (via FilesystemSource, or out of a special archive format.

Required Methods§

Source

fn get_uri(&self) -> &str

The path that this Source originates from. Only used for debug purposes.

Source

fn has_package(&self, package_name: &str) -> bool

Returns true if the Source has a package of the given name, otherwise returns false

Source

fn list_packages(&mut self) -> Vec<String>

Returns a list of all packages available in this Source. Do not call this repeatedly!

Source

fn read_file<'a>( &'a mut self, package_name: &str, pathname: &str, ) -> Result<Box<dyn ReadSeek + 'a>, PackageError>

Returns a Read + Seek for the file at the given pathname, if one exists.

Source

fn iter_entries<'a>( &'a mut self, package_name: &str, type_folder: &str, ) -> Box<dyn Iterator<Item = Result<String, PackageError>> + 'a>

Returns an iterator through the items in a given package, if the Source has said package

Source

fn trust_level(&self, package_name: &str) -> TrustLevel

Returns the source’s trust level for the given package. Trusted sources are able to load resource types marked as requiring trust.

Provided Methods§

Source

fn write_file<'a>( &'a mut self, package_name: &str, pathname: &str, ) -> Result<Box<dyn Write + 'a>, PackageError>

Returns a Write for the file at the given pathname.
