Struct Label 

#[non_exhaustive]
pub struct Label {
    pub span: Span,
    pub message: String,
}

A span with a message, pointing at source text.

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.

span: Span

The source range.

message: String

What this label says about the range (may be empty).
