warning unused

What it means#

An import, a local variable or a dependency in [deps] is never used (§2.2, part III.4). Besides the noise, an unused dep pulls code into the build for no reason. This is a warning by default, configurable in [lint].

Example#

use std.time { Duration }      // <- unused

fn main() {
  print("hi")
}

unused

How to fix#

fn main() {
  print("hi")
}

Delete the declaration, or use it. Names that are intentionally unused may be started with _.
