Required methods

If Self::SIZE.is_some(), this must return the same value. The default implementation is Self;:SIZE.unwrap().

Read the size from an on-page entry. If Self::SIZE.is_some() this must be the same value.

[src]

unsafe fn write_to_page(&self, p: *mut u8)

Write to a page. Must not overwrite the allocated size, but this isn’t checked (which is why it’s unsafe).
