How does this compare to the Rust Programming book?
Ownership. References. Expressions. Error Handling. Enums & Patterns. Operator Overloading. Closures. Iterators. Collections. Strings & Text. Input & Output. Concurrency. Macros. Unsafe Code/FFI - the coolest part, they show you how to create a safe wrapper around libgit2.

I think both are good books, I already have the second one and preordered the first.
