Comment:

 I think this looks good, though I might be missing subtle things because
 I'm still rather new to Rust.

 Minor documentation clarity nits:
 * The "Note" in the documentation for `cstr!` refers to "the above code
 compiles", but it actually means the first out of three examples rather
 than the example immediately preceding it.  Maybe replace it with "the
 first example above compiles"?
 * In that same "Note", "symbols table" should probably be "symbol table"
 (unless it's idiomatic in Rust documentation to use plural "symbols"
 there)
 These are fairly minor so feel free to merge as is or without further
 review after fixing the nits.
