Types

Loader

opaque </>

pub opaque type Loader

LoaderError

</>

pub type LoaderError {
  CompileFailed(identity.DefinitionRef, message: String)
  LoadFailed(identity.DefinitionRef, message: String)
}

Constructors

CompileFailed(identity.DefinitionRef, message: String)

LoadFailed(identity.DefinitionRef, message: String)

Values

describe

</>

pub fn describe(error: LoaderError) -> String

ensure_loaded

</>

pub fn ensure_loaded(
  ld: Loader,
  ref: identity.DefinitionRef,
  def: ast.Definition,
) -> Result(Loader, #(Loader, LoaderError))

exports

</>

pub fn exports(
  ref: identity.DefinitionRef,
) -> Result(List(#(String, Int)), String)

Export table of the ref’s loaded module, sorted. Locks the compiler’s export contract (every definition exports '$eval'/0, plus ability op stubs) and backs introspection such as run --json on a function.

is_loaded

</>

pub fn is_loaded(ld: Loader, ref: identity.DefinitionRef) -> Bool

module_available

</>

pub fn module_available(ref: identity.DefinitionRef) -> Bool

True when the ref’s compiled module is already present in this runtime, so loading it is a no-op and the store need not hold it. Genesis builtins ship as m_*.erl sources compiled into the build and the escript archive.

new_loader

</>

pub fn new_loader() -> Loader

new_loader_with_limit

</>

pub fn new_loader_with_limit(limit: Int) -> Loader
