Stabilize `std::{rc,sync}::Weak::{weak_count, strong_count}` * Original PR: rust-lang#56696 * Tracking issue: rust-lang#57977 Closes: rust-lang#57977 Supporting comments: > Although these were added for testing, it is occasionally useful to have a way to probe optimistically for whether a weak pointer has become dangling, without actually taking the overhead of manipulating atomics. Are there any plans to stabilize this? _Originally posted by @bdonlan in rust-lang#57977 (comment) > Having this stabilized would help. Currently, the only way to check if a weak pointer has become dangling is to call `upgrade`, which is by far expensive. _Originally posted by @glebpom in rust-lang#57977 (comment) Not sure if stabilizing these warrants a full RFC, so throwing this out here as a start for now. Note: per CONTRIBUTING.md, I ran the tidy checks, but they seem to be failing on unchanged files (primarily in `src/stdsimd`).

…type-parameter, r=estebank Indicate origin of where type parameter for uninferred types Based on rust-lang#65951 (which is not merge yet), fixes rust-lang#67277. This PR improves a little the diagnostic for code like: ``` async fn foo() { bar().await; } async fn bar<T>() -> () {} ``` by showing: ``` error[E0698]: type inside `async fn` body must be known in this context --> unresolved_type_param.rs:9:5 | 9 | bar().await; | ^^^ cannot infer type for type parameter `T` declared on the function `bar` | ... ``` (The ``` declared on the function `bar` ``` part is new) A small side note: `Vec` and `slice` seem to resist this change, because querying `item_name()` panics, and `get_opt_name()` returns `None`. r? @estebank
