Multiple associated values for an enum

[Sze]

Just use something like this and add 1 to it, to get the length for a dense array:

Get last value of enum

If you want to do the manual approach, you can just define a declaration like so: const MyEnum = enum(u32) { a = 0, b = 1, c = 2, pub const last: MyEnum = .c; }; // Usage: // const maximum: MyEnum = .last; If you want a more general solution, @swenninger’s strategy is close, but isn’t quite complete. The order of the fields provided by @typeInfo is based on the order that they are declared in the file, not their values. So, you would need to check the value of every field an…

Or use std.enums.directEnumArrayLen

Ahh ok, you want array indexing directly via enums.
