Compilation error

[kinire98]

I'm trying to use only the sync api, because I don't need the async one. So I don't want to pull the async runtime, and I copied the following content in my Cargo.toml, as the Docs.rs page said:
cacache = { version = "12.0.0", default-features = false, features = ["mmap"] }
And I got the following error log:

This is the neofetch information of my PC if it is useful:

I don't know if I have to change something for it to work. If I just write:
cacache = "12.0.0"
works normally, but imports the whole async runtime.

Looks like we neglected to flag some methods as being async-only. For example, https://github.com/zkat/cacache-rs/blob/main/src/index.rs#L417-L431 should have a line like https://github.com/zkat/cacache-rs/blob/main/src/index.rs#L353 on it.

How would you feel about going through these errors and feature flagging the appropriate straggler async methods? It seems to only be a couple of them.

Ok, I could look them up. I don't usually contribute to open source a lot. Any suggestions?
