Compilation error: ErrorMessage

API Rust

Hello. I’m trying to compile code which depends on sn_api = "0.24.0". I get an error in sn_api:

% cargo build  --target=i686-unknown-linux-gnu
   Compiling sn_api v0.24.0

error: could not compile `sn_api`

To learn more, run the command again with --verbose.

I don’t understand, why I get it? Wouldn’t it stop sn_api to pass CI checks?

Have you checked you version of Rust? I think they use latest stable release.

I updated from 1.49 to 1.51, but the error is the same. Also, I noticed that I copy-pasted result from wrong sn_api version, although 0.24.0 is still the same as 0.22.0, same error which makes things additionally strange, that there is an error nobody has noticed for 2 versions. That makes me think it’s only error on my computer, but I have no idea where it can come from.

I think I nailed it:

In commit 8a4f1e2e there is change in sn_client errors.rs file, that makes version 0.52.19 incompatible with sn_api, which in Cagro.toml has sn_client = "~0.52.16". This allows 0.52.19 and somehow this is the version my compiler tries to compile.

Backwards compatibility isn’t strictly enforced at the moment so previous minor versions might break with incompatible dependent versions. If you are relying on a sn_api, I would recommend pinning on the latest version
