December 29, 2021 Mixin a function into a struct only if no member with that name already exists | ||||
|---|---|---|---|---|
| ||||
 | I am trying to implement the builder pattern for some structs. Currently I am auto implementing all methods by mixing them into the builder, but now I need some custom logic for some of the fields and I figured I just write them down by hand and mixin the rest. I tried checking if it is contained in the FieldNameTuple, but that (understandably) creates a circular reference: https://run.dlang.io/is/Xih7yP How do I mixin a function only if it is not already present? | |||

Perhaps use opDispatch? That's a great idea and I'll look into it. | |||

This is the default behavior of template mixins.
