Struct TypeTable 

pub struct TypeTable { /* private fields */ }

Implementations

impl TypeTable

pub fn new() -> Self

pub fn get(&self, id: ExprId) -> &InferredType

pub fn get_opt(&self, id: ExprId) -> Option<&InferredType>

pub fn set(&mut self, id: ExprId, ty: InferredType)

pub fn snapshot(&self) -> Vec<(ExprId, InferredType)>

Returns a snapshot of all types. The snapshot is a Vec ordered by insertion — used for fix-point convergence checks (O(n) clone of InferredType values, not a tree clone).

pub fn same_as(&self, other: &TypeTable) -> bool

Returns true if this TypeTable has the same types as other. Used to detect convergence in the fix-point loop.

pub fn same_as_snapshot(&self, snapshot: &[(ExprId, InferredType)]) -> bool

Returns true if the current state matches a previously taken snapshot.
