Implementations

impl ScopeTree

pub fn build(program: &Program, source: &str) -> Self

Build a scope tree from a parsed program.

pub fn references_of(&self, offset: usize) -> Option<Vec<(usize, usize)>>

Find all references to the binding at the given byte offset.

Returns the definition span + all reference spans, or None if no binding is found at the offset.

pub fn definition_of(&self, offset: usize) -> Option<(usize, usize)>

Find the definition span of the binding at the given byte offset.

pub fn binding_at(&self, offset: usize) -> Option<&Binding>

Return the binding (definition + references) visible at the given offset. Used by hover to resolve shadowed variables correctly.
