An import was unresolved.
Erroneous code example:
use something::Foo; // error: unresolved import `something::Foo`.
Paths in use
statements are relative to the crate root. To import items relative to the current and parent modules, use the self::
and super::
prefixes, respectively. Also verify that you didn't misspell the import name and that the import exists in the module from where you tried to import it. Example:
use self::something::Foo; // ok! mod something { pub struct Foo; } # fn main() {}
Or, if you tried to use a module from an external crate, you may have missed the extern crate
declaration (which is usually placed in the crate root):
extern crate core; // Required to use the `core` crate use core::any; # fn main() {}
