Auto merge of #95977 - FabianWolff:issue-92790-dead-tuple, r=estebank
Warn about dead tuple struct fields Continuation of #92972. Fixes #92790. The language team has already commented on this in https://github.com/rust-lang/rust/pull/92972#issuecomment-1021511970; I have incorporated their requests here. Specifically, there is now a new allow-by-default `unused_tuple_struct_fields` lint (name bikesheddable), and fields of unit type are ignored (https://github.com/rust-lang/rust/pull/92972#issuecomment-1021815408), so error messages look like this: ``` error: field is never read: `1` --> $DIR/tuple-struct-field.rs:6:21 | LL | struct Wrapper(i32, [u8; LEN], String); | ^^^^^^^^^ | help: change the field to unit type to suppress this warning while preserving the field numbering | LL | struct Wrapper(i32, (), String); | ~~ ``` r? `@joshtriplett`
