Struct SyncUnsafeCell

Source

pub struct SyncUnsafeCell<T: ?Sized>(/* private fields */);

Expand description

A Sync UnsafeCell when T is Sync. “Manually stabilized” from rustc feature gate sync_unsafe_cell.

Should be replaced with core::cell::SyncUnsafeCell instead when it’s stabilized. Tracked in the rust-lang issue #95439. The open questions don’t seem to imply any issues with the type as it’s implemented here (this type requires T to be Sync, and the naming question is irrelevant for safety).
