Struct ScopeIndex 

pub struct ScopeIndex { /* private fields */ }

Implementations

impl ScopeIndex

pub fn is_empty(&self) -> bool

pub fn def_starts(&self) -> Vec<usize>

0-based start rows of every definition, sorted and deduped.

pub fn def_span(&self, name: &str) -> Option<(usize, usize)>

0-based inclusive row span of the definition called name.

pub fn enclosing(&self, line: usize) -> Option<(&str, usize, usize)>

The innermost definition enclosing line (0-based): its name and its inclusive row span.

pub fn crumbs(&self, line: usize) -> Vec<String>

Names of the definitions enclosing line (0-based), outermost first. A line inside class A → method → body returns ["A", "method"].
