Struct Hint 

#[non_exhaustive]
pub struct Hint {
    pub message: String,
    pub location: Option<SourceLocation>,
}

A hint attached to a Diagnostic.

Most hints are general advice and carry no location. Some instead point at a secondary piece of code related to the diagnostic — for those, location is set to where that code lives.

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.

message: String

The hint message.

location: Option<SourceLocation>

Where the hint points, when it refers to a secondary piece of code.
