Struct rustc_mir::monomorphize::collector::RootCollector

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

Fields

tcx: TyCtxt<'tcx>

mode: MonoItemCollectionMode

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

entry_fn: Option<(LocalDefId, EntryFnType)>

Implementations

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

pub(in monomorphize::collector) fn is_root(
    &self,
    def_id: LocalDefId
) -> bool

pub(in monomorphize::collector) 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.)

pub(in monomorphize::collector) 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.
