Description
Code
mod delicious_snacks { use self::fruits::PEAR as fruit; mod fruits { pub const PEAR: &str = "Pear"; pub const APPLE: &str = "Apple"; } } fn main() { println!("favorite snack: {} ", delicious_snacks::fruit,); }Current output

the "you could import this directly" is incorrect, maybe not as important.
having no help could be fine.
the help message is wrong in 2 important ways :
- the
fruitsmodule does not have afruitconstant. (it got confused by the alias) - the
fruitsmodule is not accessible from line 11
