Struct Problem 

#[non_exhaustive]
pub struct Problem {
    pub subject: String,
    pub message: String,
}

One thing wrong with an application’s declaration.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

subject: String

The route or setting it is about ("GET /admin", "host").

message: String

What is wrong and what to do.
