source · 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§
source§impl<'v> RootCollector<'_, 'v>
impl<'v> RootCollector<'_, 'v>
fn process_item(&mut self, id: ItemId)
fn process_impl_item(&mut self, id: ImplItemId)
fn is_root(&self, def_id: LocalDefId) -> bool
sourcefn push_if_root(&mut self, def_id: LocalDefId)
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.)
sourcefn push_extra_entry_roots(&mut self)
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.

Layout§
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
