Parameters
Name | Description |
---|---|
iter | the entity to convert into an AliasSeq . It must be able to be able to be iterated over using

import std .algorithm .iteration : map;
import std .algorithm .sorting : sort;
import std .string : capitalize;
struct S
{
int a;
int c;
int b;
}
alias capMembers = aliasSeqOf!([__traits(allMembers, S)] .sort() .map!capitalize());
static assert(capMembers[0] == "A");
static assert(capMembers[1] == "B");
static assert(capMembers[2] == "C");
Example
static immutable REF = [0, 1, 2, 3];
foreach (I, V; aliasSeqOf!([0, 1, 2, 3]))
{
static assert(V == I);
static assert(V == REF[I]);
