Struct L2Sync

Source 
pub struct L2Sync<T> {
    data: SyncUnsafeCell<T>,
}
Expand description

All L2Sync objects are guaranteed to be synchronized on the epilogue level.

Fields§

§data: SyncUnsafeCell<T>

Implementations§

Source§

impl<T> L2Sync<T>

Source

pub const fn new(data: T) -> Self

Source

pub fn lock(&self) -> L2Guard<'_, T>

Source

pub unsafe fn get_ref_unguarded(&self) -> &T

This breaks synchronization, the caller is responsible of checking the global L2_AVAILABLE flag, and do other stuffs (like relaying) when epilogue level is occupied.

Source

pub unsafe fn get_ref_mut_unguarded(&self) -> &mut T
