pub fn size(&self) -> usize[src]
If Self::SIZE.is_some(), this must return the same
value. The default implementation is Self;:SIZE.unwrap().
pub unsafe fn onpage_size(*const u8) -> usize[src]
Read the size from an on-page entry. If Self::SIZE.is_some()
this must be the same value.
pub unsafe fn write_to_page(&self, p: *mut u8)[src]
Write to a page. Must not overwrite the allocated size, but this isn’t checked (which is why it’s unsafe).
pub unsafe fn from_raw_ptr<'a, T>(&T, p: *const u8) -> &'a Self[src]
