Struct rustc_mir::monomorphize::collector::RootCollector

struct RootCollector<'a, 'tcx> {
    tcx: TyCtxt<'tcx>,
    mode: MonoItemCollectionMode,
    output: &'a mut Vec<Spanned<MonoItem<'tcx>>>,
    entry_fn: Option<(DefId, EntryFnType)>,
}

Fields

tcx: TyCtxt<'tcx>

mode: MonoItemCollectionMode

output: &'a mut Vec<Spanned<MonoItem<'tcx>>>

entry_fn: Option<(DefId, EntryFnType)>

Implementations

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

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

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.)

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.
