Consider this snippet: ```rust use std::marker::PhantomData; use std::ops::Deref; struct Lazy<T, F/* = fn() -> T*/>(F, PhantomData<T>); impl<T, F> Lazy<T, F> { pub fn new(f: F) -> Lazy<T, F> { Lazy(f, PhantomData) } } impl<T, F: FnOnce() -> T> Deref for Lazy<T, F> { type Target = T; fn deref(&self) -> &T { todo!() } } fn test() { let lazy1: Lazy<u32, _> = Lazy::new(|| 0u32); let r1 = lazy1.to_string(); fn make_u32_fn() -> u32 { todo!() } let make_u32_fn_ptr: fn() -> u32 = make_u32_fn; let lazy2: Lazy<u32, _> = Lazy::new(make_u32_fn_ptr); let r2 = lazy2.to_string(); } ``` * On current master: * When type default is commented-out, `r1` is correctly inferred, `r2` in _{unknown}_. * When type default is not commented-out, both `r1` and `r2` are _{unknown}_. * With this PR: * When type default is commented-out, both `r1` and `r2` are correctly inferred. * When type default is not commented-out, both `r1` and `r2` are _{unknown}_. Well, it's a improvement at least. I guess this thing with type defaults is a different problem. I also tried add Fn impls for fn items, but wasn't successful. So this PR only adds those impls for fn pointers. Co-authored-by: Hrvoje Ban <[email protected]>

|\ \ | | | | | | | | | | | | | | | | | | | | | 4479: Chalk upgrade r=matklad a=flodiebold This includes the fix for `dyn Trait` super traits, but I noticed that still a lot of `db.super_trait_method()` calls don't work because the super trait isn't in scope (because it doesn't actually need to be). Somehow, I thought we handled that already, but I'll fix it in a separate PR. Also I'll see what happens if we use more of Chalk's new built-in types and traits in a separate PR.

It mostly works, but I'm sure there are some cases that I missed, especially in regards to parameter type. Note: I'm playing with this this as a way to learn Rust and this project. So I'm sure it could be cleaner and put in better places`. Any suggestions? Co-authored-by: zbsz <[email protected]>

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 4448: Generate configuration for launch.json r=vsrs a=vsrs This PR adds two new commands: `"rust-analyzer.debug"` and `"rust-analyzer.newDebugConfig"`. The former is a supplement to the existing `"rust-analyzer.run"` command and works the same way: asks for a runnable and starts new debug session. The latter allows adding a new configuration to **launch.json** (or to update an existing one). If the new option `"rust-analyzer.debug.useLaunchJson"` is set to true then `"rust-analyzer.debug"` and Debug Lens will first look for existing debug configuration in **launch.json**. That is, it has become possible to specify startup arguments, env variables, etc. `"rust-analyzer.debug.useLaunchJson"` is false by default, but it might be worth making true the default value. Personally I prefer true, but I'm not sure if it is good for all value. ---- I think that this PR also solves https://github.com/rust-analyzer/rust-analyzer/issues/3441. Both methods to update launch.json mentioned in the issue do not work: 1. Menu. It is only possible to add a launch.json configuration template via a debug adapter. And anyway it's only a template and it is impossible to specify arguments from an extension. 2. DebugConfigurationProvider. The exact opposite situation: it is possible to specify all debug session settings, but it is impossible to export these settings to launch.json. Separate `"rust-analyzer.newDebugConfig"` command looks better for me. ---- Fixes #4450 Fixes #3441 Co-authored-by: vsrs <[email protected]> Co-authored-by: vsrs <[email protected]>
