Implementations§

source§

impl<'v> RootCollector<'_, 'v>

source

fn process_item(&mut self, id: ItemId)

source

fn process_impl_item(&mut self, id: ImplItemId)

source

fn is_root(&self, def_id: LocalDefId) -> bool

source

fn push_if_root(&mut self, def_id: LocalDefId)

If def_id represents a root, pushes it onto the list of outputs. (Note that all roots must be monomorphic.)

source

fn push_extra_entry_roots(&mut self)

As a special case, when/if we encounter the main() function, we also have to generate a monomorphized copy of the start lang item based on the return type of main. This is not needed when the user writes their own start manually.
