No rustdoc anywhere

Docs.rs says that the build failed for 0.7.2, and there's no documentation link on crates.io. Taken together, this means that there seems to be no publicly available reference documentation for this library, which is obviously not ideal.

Start by checking why the docs.rs build for version 0.7.2 failed and whether the crate metadata exposes documentation on crates.io. The work is done when the library has publicly available reference documentation and the crates.io documentation link is present.
