pub struct RawIter<T> { /* private fields */ }
raw
only.Expand description
Iterator which returns a raw pointer to every full bucket in the table.
For maximum flexibility this iterator is not bound by a lifetime, but you must observe several rules when using it:
- You must not free the hash table while iterating (including via growing/shrinking).
- It is fine to erase a bucket that has been yielded by the iterator.
- Erasing a bucket that has not yet been yielded by the iterator may still
result in the iterator yielding that bucket (unless
reflect_remove
is called). - It is unspecified whether an element inserted after the iterator was
created will be yielded by that iterator (unless
reflect_insert
is called). - The order in which the iterator yields bucket is unspecified and may change in the future.

§impl<T> RawIter<T>
impl<T> RawIter<T>
pub unsafe fn reflect_remove(&mut self, b: &Bucket<T>)
pub unsafe fn reflect_remove(&mut self, b: &Bucket<T>)
Refresh the iterator so that it reflects a removal from the given bucket.
For the iterator to remain valid, this method must be called once
for each removed bucket before next
is called again.
This method should be called before the removal is made. It is not necessary to call this method if you are removing an item that this iterator yielded in the past.
pub unsafe fn reflect_insert(&mut self, b: &Bucket<T>)
pub unsafe fn reflect_insert(&mut self, b: &Bucket<T>)
Refresh the iterator so that it reflects an insertion into the given bucket.
For the iterator to remain valid, this method must be called once
for each insert before next
is called again.
This method does not guarantee that an insertion of a bucket with a greater index than the last one yielded will be reflected in the iterator.
This method should be called after the given insert is made.
