Struct ChunkBy
#[must_use = "iterator adaptors are lazy and do nothing unless consumed"]
pub struct ChunkBy<K, I, F>
where
I: Iterator, { /* private fields */ }ChunkBy is the storage for the lazy grouping operation.
If the groups are consumed in their original order, or if each
group is dropped without keeping it around, then ChunkBy uses
no allocations. It needs allocations only if several group iterators
are alive at the same time.
This type implements IntoIterator (it is not an iterator
itself), because the group iterators need to borrow from this
value. It should be stored in a local variable or temporary and
iterated.
See .chunk_by() for more information.
