Crate Features

The ockam crate has a Cargo feature named "std" that is enabled by default. In order to use this crate in a no_std context this feature can disabled as follows

ockam = { version = "0.7.0", default-features = false }

Please note that Cargo features are unioned across the entire dependency graph of a project. If any other crate you depend on has not opted out of ockam default features, Cargo will build ockam with the std feature enabled whether or not your direct dependency on ockam has default-features = false.
