Summary: Implement getPair() for Associative Arrays Product: D Version: D2 Platform: All OS/Version: All Status: NEW Severity: enhancement Priority: P2 Component: druntime AssignedTo: nob...@puremagic.com ReportedBy: andrej.mitrov...@gmail.com --- Comment #0 from Andrej Mitrovic <andrej.mitrov...@gmail.com> 2013-02-24 16:44:21 PST --- This was requested recently in IRC. A getPair() function would return a key+val combination from an existing key (ideally as a struct), e.g.: void main() { string buffer = "abc def"; string abc = buffer[0 .. 3]; bool[string] hash; hash[abc] = true; auto pair = hash.getPair("abc"); // enhancement assert(pair.key is abc); // L9 assert(pair.val == true); // not the same as: alias Tuple!(string, "key", bool, "val") Tup; Tup tup; tup.key = "abc"; tup.val = hash["abc"]; assert(tup.key is abc); // this would fail assert(tup.val == true); } Note the importance of line 9, it is an 'is' check, not an equality check. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
