root: ModuleSpecifier

Implementations

impl ModuleGraph

pub fn new(
    root: ModuleSpecifier,
    maybe_locker: Option<Rc<RefCell<dyn Locker>>>
) -> Self

pub fn get(&self, specifier: &ModuleSpecifier) -> Option<&Module>

Get a module from the module graph, returning None if the module is not part of the graph, or if when loading the module it errored. If any module resolution error is needed, then use the try_get() method which will return any resolution error as the error in the result.

pub fn lock(&self) -> Result<(), ModuleGraphError>

Determine if the graph sources are valid by calling the passed locker. If the integrity of all the sources passes or if there is no locker supplied the method results in an ok, otherwise returns an error which indicates the first specifier that failed the integrity check.

pub fn resolve(&self, specifier: &ModuleSpecifier) -> ModuleSpecifier

Resolve a specifier from the module graph following any possible redirects returning the “final” module.

pub fn resolve_dependency(
    &self,
    specifier: &str,
    referrer: &ModuleSpecifier
) -> Option<&ModuleSpecifier>

Resolve a dependency of a referring module providing the string specifier of the depdency and returning an optional fully qualified module specifier.

pub fn try_get(
    &self,
    specifier: &ModuleSpecifier
) -> Result<Option<&Module>, ModuleGraphError>

Retrieve a module from the module graph. If the module identified as a dependency of the graph, but resolving or loading that module resulted in an error, the error will be returned as the Err of the result. If the module is not part of the graph, or the module is missing from the graph, the result will be Ok with the option of the module.
