Struct Source 

#[non_exhaustive]
pub struct Source {
    pub file: &'static str,
    pub line: u32,
    pub from_library: bool,
}

Recorded source location for an element. Set automatically via #[track_caller] on every constructor.

from_library distinguishes Els constructed inside aetna’s own widget closures (where the closure boundary defeats #[track_caller] and the recorded location lands inside aetna-core instead of at the user’s call site) from Els constructed in user code. The lint pass uses this to gate user-facing findings and to walk blame attribution upward to the nearest user-source ancestor. Set explicitly via crate::tree::El::from_library at the few closure-builder sites that need it.

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.
