debug-fmt-detail option

I'd like to propose a new option that makes #[derive(Debug)] generate no-op implementations that don't print anything, and makes {:?} in format strings a no-op.

There are a couple of motivations for this:

A more thorough stripping of debug symbols. Binaries stripped of debug symbols still retain some of them through Debug implementations. It's hard to avoid that without compiler's help, because debug formatting can be used in many places, including dependencies, and their loggers, asserts, panics, etc.
- In my testing it gives about 2% binary size reduction on top of all other binary-minimizing best practices (including panic_immediate_abort). There are targets like Web WASM or embedded where users pay attention to binary sizes.
- Users distributing closed-source binaries may not want to "leak" any symbol names as a matter of principle.
Adds ability to test whether code depends on specifics of the Debug format implementation in unwise ways (e.g. trying to get data unavailable via public interface, or using it as a serialization format). Because current Rust's debug implementation doesn't change, there's a risk of it becoming a fragile de-facto API that won't be possible to change in the future. An option that "breaks" it can act as a grease.

This implementation is a -Z debug-fmt-detail=opt flag that takes:

full — the default, current state.
none — makes derived Debug and {:?} no-ops. Explicit impl Debug for T implementations are left unharmed, but {:?} format won't use them, so they may get dead-code eliminated if they aren't invoked directly.
shallow — makes derived Debug print only the type's name, without recursing into fields. Fieldless enums print their variant names. {:?} works.

The shallow option is a compromise between minimizing the Debug code, and compatibility. There are popular proc-macro crates that use Debug::fmt as a way to convert enum values into their Rust source code.

There's a corresponding cfg flag: #[cfg(debug_fmt_detail = "none")] that can be used in user code to react to this setting to minimize custom Debug implementations or remove unnecessary formatting helper functions.

I'd love to see this happen.

I have a suggestion for a refinement: In the none case, I think it might be better to write a constant string rather than the empty string. While this does slightly negate the code-size benefit, it will aid debuggability to get a recognizable string rather than a mysteriously empty one (because many different bugs can cause empty strings, and the empty string might even be used intentionally with the expectation that no value's Debug representation is the empty string).

This constant string should be "[object Object]" — just kidding. Maybe something like "<disabled>", "{debug-fmt-detail=none}", or perhaps, for minimality while still using Rust idiom,"_".

@kpreid But none isn't merely writing an empty string. It makes Debug::fmt an empty function that doesn't touch the Formatter, which makes it possible to optimize it entirely.

There is LoweringContext::lower_format_args that maybe could replace {:?} with a string literal. However, it needs to keep the arg expressions for their side effects. Perhaps the args could be changed to something like drop(&arg) or (&arg, "").1, but I wasn't able to figure out how to transform the expressions. It needs to modify FormatArgs with ast::Expr, but the lower_format_args seems to have access only to hir::Expr.

I suggest dropping the "detail" from the name. We have similar options like -C debuginfo and they are not called -C debuginfo-level or -C debuginfo-detail, it's already clear from the possible values (and -C already says that it's about codegen).

(Also maybe debug_fmt -> fmt_debug to match the trait/macro path std::fmt::Debug.)
