pub struct OutputTypes(BTreeMap<OutputType, Option<OutFileName>>);
Expand description

Use tree-based collections to cheaply get a deterministic Hash implementation. Do not switch BTreeMap out for an unsorted container type! That would break dependency tracking for command-line arguments. Also only hash keys, since tracking should only depend on the output types, not the paths they’re written to.
