typeck: if a private field exists, also check for a public method For example, `Vec::len` is both a field and a method, and usually encountering `vec.len` just means that the parens were forgotten. Fixes: #26472 2016-05-02 12:52:48 +00:00			`mod sub {`

pretty: trim paths of unique symbols If a symbol name can only be imported from one place for a type, and as long as it was not glob-imported anywhere in the current crate, we can trim its printed path and print only the name. This has wide implications on error messages with types, for example, shortening `std::vec::Vec` to just `Vec`, as long as there is no other `Vec` importable anywhere. This adds a new '-Z trim-diagnostic-paths=false' option to control this feature. On the good path, with no diagnosis printed, we should try to avoid issuing this query, so we need to prevent trimmed_def_paths query on several cases. This change also relies on a previous commit that differentiates between `Debug` and `Display` on various rustc types, where the latter is trimmed and presented to the user and the former is not. 2020-09-02 07:40:56 +00:00			let v = s.len; //~ ERROR field `len` of struct `S` is private
