https://issues.dlang.org/show_bug.cgi?id=22297 Issue ID: 22297 Summary: Behavior of minElement and maxElement with empty range is undocumented Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: normal Priority: P1 Component: phobos Assignee: nobody@puremagic.com Reporter: snarwin+bugzilla@gmail.com The documentation for minElement and maxElement does not specify what happens when either function is called with an empty range as its argument. Experimentation reveals that what happens is an assertion failure, which terminates the program: --- import std.algorithm.searching; void main() { int[] emptyArr; auto min = minElement(emptyArr); // AssertError: r is an empty range } --- This behavior should be documented. -- |
