Struct combine::stream::state::IndexPositioner

[+] Show declaration

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().
