Consider I have created a struct like mentioned bellow
struct AppKey {
name: &str,
key: &str
}
How do I implement the trait std::ops::Try
that is not implemented for AppKey

Why do you need to implement Try
for it? That trait is only meant for types that contain successes or failures (like Option
and Result
.)
The first thing to realize is that Try
is an unstable feature, and it requires nightly if you wish to implement it for your own type.
The second thing to realize is that it doesn't appear to make much sense to implement Try
for your type. What are the ok and error cases for that struct?
I assume you got the idea of implementing Try
from an error message about using ?
. Perhaps you should tell us about this case, so we can point you towards a better appraoch.
