It seems like some additional dead code analysis was introduced in the most recent nightly:
warning: field `0` is never read
--> FastWaveBackend/src/vcd/reader.rs:12:24

12 | pub(super) struct Line(pub(super) usize);
| ---- ^^^^^^^^^^^^^^^^
| |
| field in this struct
|
= note: `Line` has derived impls for the traits `Clone` and `Debug`, but these are intentionally ignored during dead code analysis
= note: `#[warn(dead_code)]` on by default
help: consider changing the field to be of unit type to suppress this warning while preserving the field numbering, or remove the field
