04:48 <RockBoynton[m]> Are there any Rust conferences coming up where there will be talks by embedded folks?

04:55 <M9names[m]> isn't that pretty much every rust conference?

05:05 <M9names[m]> there aren't many conferences i know of in the immediate future. looks like the next is going to be rust nation UK at the end of feb, they only have most of 1 day of schedule listed, and there's only 2ish talks that might be vaguely embedded

05:13 <adamgreig[m]> huh, you can tell cargo to pass `--print-memory-usage` to `ld` and get a nice per-region breakdown of usage:...

05:14 <adamgreig[m]> by default cargo eats the output but RUSTC_LOG=rustc_codegen_ssa::back::link=info will show it, wonder if there's a neater way

05:19 <adamgreig[m]> it seems like "doesn't show linker output" is an open bug from 2016 https://github.com/rust-lang/rust/issues/38206 but https://github.com/rust-lang/rust/pull/119286 looks like it might merge soon and puts linker stderr/stdout out of normal -v

05:20 <adamgreig[m]> so maybe within a version or two of rust you can just stick that in your cargo config and get nice memory usage reports

05:21 <adamgreig[m]> I think it's a lot clearer than the output of size

11:37 <JamesMunns[m]> <RockBoynton[m]> "Are there any Rust conferences..." <- Oxidize and RustNL tend to lean more embedded, but as 9names said, most confs have one or two usually these days

17:18 <Mathias[m]> Other example: FOSDEM will be like that https://fosdem.org/2025/schedule/track/rust/

17:19 <thejpster[m]> Should items be pub(crate) be default?

17:20 <thejpster[m]> I was at Oxidize, RustNL, RustConf, EuroRust and Rust Nation. I think they all had some embedded component. Sometimes it wasn’t even from me.

17:24 <thejpster[m]> PSA: I am submitting zero conference talks in 2025 and I am attending only two conferences and they are both Oxidize and that’s only because I’m teaching workshops there.

17:24 <thejpster[m]> If you want to see embedded content in 2025 then be the change you want to see. I’m tired.

18:58 <diondokter[m]> I intend to submit an embedded related talk for RustNL. But of course that might not be accepted, so if anybody has an idea, do submit!

20:19 <igiona[m]> <adamgreig[m]> "huh, you can tell cargo to pass..." <- I tried

20:19 <igiona[m]> RUSTFLAGS="-C link-arg=--print-memory-usage" RUSTC_LOG=rustc_codegen_ssa::back::link=info cargo build

20:19 <igiona[m]> But I still don't see anything... how to you pass --print-memory-usage?

20:20 <bogdan[m]> <thejpster[m]> "PSA: I am submitting zero..." <- I think I understand and respect that. But just as a side note, I really enjoyed your SD driver presentation at EuroRust -- the playful, knowledgeable and enthusiastic manner of your presentation reminded me why I (voluntarily) picked working in embedded programming. Thanks for that!

21:13 <adamgreig[m]> <igiona[m]> "I tried..." <- that looks ok, i'm doing it in build.rs with `println!("cargo:rustc-link-arg=--print-memory-usage");` but it should be fine in `cargo.toml` with `"-C", "link-arg=--print-memory-usage"` I expect?

21:19 <dirbaio[m]> I think Cargo or rustc doesn't show linker output by default? you might have to try -v or similar

21:20 <adamgreig[m]> that's the RUSTC_LOG=rustc_codegen_ssa::back::link=info bit

21:20 <adamgreig[m]> <adamgreig[m]> "it seems like "doesn't show..." <- `cargo -v` doesn't yet, but hopefully soon
