digitalmars.D.learn - Dynamically init a struct with values calculated from other values in the struct?
- =?iso-8859-1?Q?Robert_M._M=FCnch?= (17/17) Apr 04 2020 I need to dynamically initialize a fixed number of entries of the form:
- Steven Schveighoffer (4/23) Apr 04 2020 I recommend using a factory function or ctor.
I need to dynamically initialize a fixed number of entries of the form: (start, length) and iterate over them. Hence, I think a struct makes sense: struct S { s1, l1 , s2, l2 , s3, l3 } Now I need to initialize the values like this: S myS = {s1:0, l1:10, s2:(2*s1), ...}; So I somehow would like to reference the prior values to initialize the other members. I haven't found a way to do it. Is this possible at all? Or do I just init the struct empty and then set the entries? -- Robert M. Münch http://www.saphirion.com smarter | better | faster
