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

Fields

tcx: TyCtxt<'tcx>mode: MonoItemCollectionModeoutput: &'a mut MonoItems<'tcx>entry_fn: Option<(DefId, EntryFnType)>

Implementations

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.

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.
