I want to port in serde_json through cucumber. gherkin_rust v0.10.1 lists it under "[build-dependencies]". How do I access it without adding it to the toml file / using an extern crate call?

You can not access to it through another crate unless that other crate reexports it publicly (ex pub use::cool_crate).

Just add whatever you need to your Cargo.toml. Notice that dependencies are not used more than once, so there should not be any difference but the usage through namespacing.
