Expand description
The output type for iterators in Koto
Variants§
Value(KValue)
A single value
ValuePair(KValue, KValue)
A pair of values
This is used as an optimization for iterators that output pairs, like a map iterator that
outputs key/value pairs, or enumerate
.
Error(Error)
An error that occurred during iteration
Iterators that run functions should check for errors and pass them along to the caller.
