Struct rustc_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.

Trait Implementations

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

fn visit_item(&mut self, item: &'v Item<'v>)

fn visit_trait_item(&mut self, _: &'v TraitItem<'v>)

fn visit_impl_item(&mut self, ii: &'v ImplItem<'v>)

fn visit_foreign_item(&mut self, _foreign_item: &'v ForeignItem<'v>)

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.
