[−][src]Module zerogc::cell
Implements a GcCell to allow mutating values inside garbage collected objects.
Normally garbage collected objects are immutable, since their references are shared. It's typical for collectors to want to trigger a write barrier before writing to a field. All interior mutability requires triggering appropriate write barriers, which is unsafe.
The zerogc_derive
crate can generate setters
for fields that are wrapped in a GcCell.
Just mark the field with #[zerogc(mutable(public))]
and it'll generate a safe wrapper.
