}🔬This is a nightly-only experimental API. (
new_range_api)Expand description
A range only bounded inclusively below (start..).
The RangeFrom start.. contains all values with x >= start.
Note: Overflow in the Iterator implementation (when the contained
data type reaches its numerical limit) is allowed to panic, wrap, or
saturate. This behavior is defined by the implementation of the Step
trait. For primitive integers, this follows the normal rules, and respects
the overflow checks profile (panic in debug, wrap in release). Note also
that overflow happens earlier than you might assume: the overflow happens
in the call to next that yields the maximum value, as the range must be
set to a sta
