Struct okane_core::load::Loader

pub struct Loader { /* private fields */ }

Loader is an object to keep loading a given file and may recusrively load them as repr::LedgerEntry, with the metadata about filename or line/column to point the error in a user friendly manner.

Implementations

impl Loader

pub fn new(source: PathBuf) -> Self

Create a new instance of Loader to load the given path.

It might look weird to have the source path as a Loader member, but that would give future flexibility to support loading from stdio/network without include, or completely static one.

pub fn with_fake_files( &mut self, fake_files: HashMap<PathBuf, Vec<u8>>, ) -> &mut Self

Set fake_files which resolves Path -> its contents conversion.

pub fn load_repl<T, E>(&self, callback: T) -> Result<(), E>

where T: FnMut(&Path, &LedgerEntry<'_>) -> Result<(), E>, E: Error + From<LoadError>,

Loads repl::LedgerEntry and invoke callback on every entry, recursively resolving include directives.
