Im building an ident generator and I want to add it serde support. But the code GitHub - IronThread/ident_gen: A simple ident generator that lets you chose the table that use. when ran with cargo build --all-features
always throws me this error:

It throws me that error no matter if I import the macros from serde_derive
and rename them with as
. I see this as a real problem for serde
originating from rustc
. But I dont know if make an issue on serde,on rust or a comment on https://github.com/rust-lang/rust/issues/27812.
I tested only on nightly the following version:
rustc --version --verbose
:
rustc 1.71.0-nightly (458d4dae8 2023-04-25)
binary: rustc
commit-hash: 458d4dae845ec155b285681a5b88305641abb868
commit-date: 2023-04-25
host: i686-pc-windows-msvc
release: 1.71.0-nightly
LLVM version: 16.0.2
Please tell me if this is happening in other channels,thank you for your attention.
