pub static UNUSED_TUPLE_STRUCT_FIELDS: &'static Lint
unused_tuple_struct_fields lint detects fields of tuple structs
that are never read.
#[warn(unused_tuple_struct_fields)] struct S(i32, i32, i32); let s = S(1, 2, 3); let _ = (s.0, s.2);
Tuple struct fields that are never read anywhere may indicate a mistake or unfinished code. To silence this warning, consider removing the unused field(s) or, to preserve the numbering of the remaining fields, change the unused field(s) to have unit type.
