sourcepub fn sub_span_of_star(&self, span: Span) -> Option<Span>
pub fn sub_span_of_star(&self, span: Span) -> Option<Span>
Finds the span of * token withing the larger span.
sourcepub fn filter_generated(&self, span: Span) -> bool
pub fn filter_generated(&self, span: Span) -> bool
Return true if the span is generated code, and it is not a subspan of the root callsite.
Used to filter out spans of minimal value, such as references to macro internal variables.
