Struct AssignedAnalysis 

pub struct AssignedAnalysis { /* private fields */ }

The locals definitely assigned a value at each statement’s entry — the intersection over all incoming control-flow paths. A typed-no-initializer local read while absent here is a read-before-assign. The sound dual of narrowing: grow-only + intersect-at-merge, and simpler — a callee cannot assign a caller’s function-scoped local, so there is no opaque-call / aliasing / self-rooted handling (do not copy those arms from the narrowing analyzer).

Implementations

impl AssignedAnalysis

pub fn assigned_before(&self, stmt: StmtId) -> Option<&FxHashSet<SmolStr>>

The locals definitely assigned before stmt, or None if stmt was not analyzed (a statement inside a lambda body — those are left unchecked, so the caller skips them).

Trait Implementations

impl Clone for AssignedAnalysis

fn clone(&self) -> AssignedAnalysis

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AssignedAnalysis

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for AssignedAnalysis

fn default() -> AssignedAnalysis

Returns the “default value” for a type.
