Broken implementation of types


#1

Hello! I am Max Popov!
I am want to compile “Image” project by PistonDevelopers,but some dependencies was not compile.More precisely,
rand v0.3.3 throw::

type `std::io::error::Error` does not implement any method in scope named `raw_os_error`

serialize v0.3.7 throw::

type `std::path::PathBuf` does not implement any method in scope named `from`
method `index` has an incompatible type for trait: expected &-ptr, found str

Please tell me how to solve it,very thank you,because I am novice in Rust


#2
