Struct HygieneInfo 

pub struct HygieneInfo {
    pub scope_id: u64,
    pub def_site: Span,
}

Hygiene information for macro expansion.

Tracks the scope and definition site so that names introduced by the macro do not accidentally capture or shadow names in the call site.

Fields

scope_id: u64

Unique scope identifier for this macro expansion.

def_site: Span

The source location where the macro was defined.
