[ty] Infer lambda parameter types with `Callable` type context by ibraheemdev · Pull Request #24317 · astral-sh/ruff

ibraheemdev · 2026-03-30T21:04:36Z

Improves #22633 to infer the use of lambda parameters in a lambda body with type context, e.g.,

x: Callable[[str], str] = lambda x: reveal_type(x)  # revealed: str
reveal_type(x)  # revealed: (x: str) -> str

Unlike other definitions, lambda parameter types cannot be determined purely syntactically in semantic indexing. Instead, they depend on the inferred type of the lambda to access its parameter types. Unfortunately, this makes lambda inference cyclic, as the body of the lambda depends on the outer lambda type, and there is no obvious way of splitting out inference of the lambda parameter types from its return type.

To avoid initiating cycles on the entire scope containing the lambda, this PR introduces a new inference query — statement-level inference. Statements are a minimal unit of code that encapsulate any internal type context. This makes them very useful to infer a given sub-expression "naturally" without having to provide any external type context. There are other places where we currently rely on scope-level inference for this purpose (e.g., see infer_complete_scope_types, the current implementation of #23761, and the discussion in astral-sh/ty#3124). Note that statement-level inference is not perfectly fine-grained, e.g., the test expression of an if statement does not require external type context and is independent from its body, so statement-level inference may lead to unnecessarily large cycles, but having the unit of code being generalized to an AST structure allows us to avoid the need for such special cases, but this can always change in the future.

Additionally, many statements are simply wrappers around definitions or standalone expressions, so we can avoid extra salsa allocations in the common case.

I haven't looked too closely at the ecosystem report but those diagnostics look expected, as this PR increases our type inference coverage quite significantly where we would previously infer Unknown.

Awesome! 👍 to the new statement-level inference region

                }
            }
            ast::Expr::Lambda(lambda) => {
+                if let Some(current_statement) = self.current_statement_mut() {


Are there places where we could encounter a lambda that's not in some statement?

dcreager · 2026-04-21T15:10:20Z

 use rustc_hash::{FxHashMap, FxHashSet};
 use salsa;
 use salsa::plumbing::AsId;
+use ty_python_core::statement::StatementInner;


very nit: should this be down in the next section, near the other ty_python_core imports?
