Summary: std.conv.to for safer enum casts Product: D Version: D2 Platform: All OS/Version: All Status: NEW Severity: enhancement Priority: P2 Component: Phobos AssignedTo: nob...@puremagic.com ReportedBy: bearophile_h...@eml.cc --- Comment #0 from bearophile_h...@eml.cc 2011-02-01 16:22:32 PST --- If I have an enum of chars, and I have a variable that contains a generic char, I may want to convert the second to an instance of the first one. A normal cast is enough to do it unsafely, but I'd like to be allowed to use to!() to convert it safely (it may raise an error if it's not among the enum cases). An example: import std.conv: to; enum Foo : char { a = 'A', b = 'B' } void main() { Foo r1 = cast(Foo)'A'; // OK Foo r2 = cast(Foo)'X'; // error undetected Foo r3 = to!Foo('A'); // OK Foo r4 = to!Foo('X'); // error detected } -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
