pub fn pack(layout: &Layout, asked: &Slice, dest: &Path) -> Result<Report>Expand description
Pack a slice of the tracker into dest.
The closure is the issues named, plus every blocker they stand on and every parent they sit under, walked to a fixed point. Children are not pulled in: handing over a plan means handing over the plan, and a parent’s other children are other people’s work.
§Errors
Returns an error when the slice names nothing, when an issue is not in the
corpus, or when dest cannot be written.
