Struct combine::stream::state::IndexPositioner
source · pub struct IndexPositioner(_);
Expand description
The IndexPositioner<Item, Range>
struct maintains the current index into the stream I
. The
initial index is index 0. Each Item
consumed increments the index by 1; each range
consumed
increments the position by range.len()
.
