Required Methods

This is called on the returned Box<dyn Any> from codegen_backend

Panics

Panics when the passed Box<dyn Any> was not returned by codegen_backend.

This is called on the returned Box<dyn Any> from join_codegen

Panics

Panics when the passed Box<dyn Any> was not returned by join_codegen.

Provided Methods

If this plugin provides additional builtin targets, provide the one enabled by the options here. Be careful: this is called before init() is called.

The metadata loader used to load rlib and dylib metadata.

Alternative codegen backends may want to use different rlib or dylib formats than the default native static archives and dynamic libraries.
