Description

rust-analyzer version: 84be2eaf9 2022-05-23 stable

rustc version: rustc 1.60.0 (7737e0b5c 2022-04-04)

relevant settings: Didn't find any

Sometimes, typing < to specify generics inserts $0, like here:

let v: Vec

The result is let v: Vec<$0>, which is invalid code.

This started happening on the latest release.

Research direction

No source file or test is named in the report. Reproduce the issue with let v: Vec and inspect rust-analyzer's handling of a typed <; done means typing the generic delimiter no longer inserts the $0 placeholder or produces invalid code.
