No, because you explained it very well. :)

Indeed, I will add some :) of this information to the Traits chapter

Although the function itself is static, it returns a dynamic value.

Sure. This is of course stripped down just for demonstration purposes:
struct Attr {
string name;
}
mixin template Model() {
static string[string] columns () {
string[string] cols;
alias type = typeof(this);
// Basica
Could you please provide complete code.
Thank you,

I need to gather some data in compile time basing on UDA.
struct Attr {
string name;
}
mixin template Model() {
static string[string] columns () {
string[string] cols;
alias type = typeof(this);
// Basically - get all members with @Attr UDA and build AA out of those
foreach(
15 matches
