crate naming, "features" in Cargo.toml about magic-wormhole.rs HOT 2 CLOSED

Yes this sounds reasonable. Most of the Rust packages uses features where there will be a default feature which is like these are sane defaults and there will be additional features which gives additional stuff. So from your explanation above it feels like core should be default feature and io-tokio is feature when user opts in for tokio dependency.

I'm not fully familiar with wormhole so not sure which should be default feature. i.e core or cli or both core and cli.

Just my 2 cents.

Ok, based on your comments and those of some other rust folks, I'm gonna aim for this:

• one crate, named magic-wormhole
• cargo install magic-wormhole gets you bin/wormhole (Cargo.toml will have a [[bin]] name = "wormhole" with path = "src/bin/main.rs")
• there are two features, named io-blocking and io-tokio, both on by default
• apps probably want to add a dependency like magic-wormhole = { version = "0.1", default-features = false, features = ["io-tokio"] }
• but if they forget, things will still work, they'll just get some spurious dependencies

I still want to see if cargo install magic-wormhole picks up the non-required IO layers, or if the required-features in our Cargo.toml is enough to avoid those.
