= help: items from traits can only be used if the trait is implemented and in scope
= note: the following trait defines an item `read`, perhaps you need to implement it:
candidate #1: `std::io::Read`
error: aborting due to 3 previous errors
Some errors have detailed explanations: E0282, E0599.
For more information about an error, try `rustc --explain E0282`.
