Possible to support delegation of Constructors? Fuctions returning Self and Result<Self, SomeErr>?

[Sajjon]

Gr8 Cr8! I would love to be able to forward all constructors as well! Do you think it would be possible?

Hi, could you please send a code example, so that I can better understand the use-case? Thanks!

Hey! Basically every non trivial NewType or type which otherwise wraps another type, and where Id prefer to not have to instantiate the inner type and call into() on it. Being able to delegate a lot of constructors would be awesome!

Eg the Hex32Bytes structure holding an inner BagOfBytes, would be nice ti delegate the TryFrom and From impl:

With rust-delegate, you can't currently delegate trait implementations, due to limitations of the Rust introspection system. You could do something like this (if it were implemented):

delegate_trait! { TryFrom, Hex32Bytes, Vec<u8>>, CommonError }

but I'm not sure if that's so much better than the hand-written impl.
