Implementations

impl Modules

pub fn new(dirs: Vec<PathBuf>, check: Check) -> Self

pub fn add(&mut self, path: PathBuf, module: LoadedModule) -> usize

Registers a module read from path, whose programs are found by name from now on; its number is what Modules::take takes.

pub fn add_first(&mut self, path: PathBuf, module: LoadedModule) -> usize

Registers the module the run began with, as Modules::add does; a program of the same source as its program 0 is loaded with no files to record, as a program of the run’s first source is.

pub fn take( &mut self, k: usize, ordinal: usize, ) -> Option<Result<LoadedProgram<Rc<Code>>, String>>

Program ordinal of module k for the run unit, checked; None once taken.

pub fn loaded( &mut self, name: &str, ) -> Option<Result<LoadedProgram<Rc<Code>>, LoadError>>

A program of a module already read that no CALL has taken, by the name a CALL gives: the first such module, and in it the lowest ordinal.

pub fn search( &mut self, name: &str, ) -> Result<LoadedProgram<Rc<Code>>, LoadError>

NAME.iwm, then name.iwm, in each directory in turn. A module found that cannot be read, or that holds no program NAME, is an error, not “not found”.

pub fn holder(&self, entry: &str) -> Option<String>

The PROGRAM-ID of a program not yet taken, of a module already read, with this ENTRY name.

pub fn loaded_class( &mut self, external: &str, ) -> Result<Option<FoundClass<Rc<ClassCode<Rc<Code>>>>>, String>

The COBOL class definition of this external name in a module already read, not yet taken.

pub fn search_class( &mut self, external: &str, ) -> Result<Option<FoundClass<Rc<ClassCode<Rc<Code>>>>>, String>

The COBOL class definition of this external name in a module named as the source search names the class’s source (numeric::assumptions::CLASS_SEARCH), in each directory in turn.

pub fn mapset(&self, name: &str) -> Option<Mapset>

A mapset a module already read holds.
