What version should we default to within a workspace?

[epage]

Currently, we default to the highest version in the workspace. What if that isn't the direct dependency but is a transitive dependency?

Options

• Pick highest
• Prioritize the parent directories package
• Prioritize if its a direct dependency of any workspace member

• Prioritize the parent directories package

What do you mean by this?
Does it depend on the directory where the command is executed?

[epage]

Just like cargo does discovery of a manifest for cargo check, select that manifest for cargo info and if the user-specified package is a direct dependency, use that version.

I think we already did this, right?

For example:

ahash is a transitive dep of cargo-information.

If you run ahash under cargo-information dir:

ahash #hash #hasher #hashmap #aes #no-std

note: to see how you depend on ahash, run `cargo tree --invert --package ahash@0.8.8`

Or I misunderstood transitive dependency?

[epage]

Say my dependency graph looks like

member1

• ahash v1
• dep1
  • ahash v3
    member2
• ahash v2
• dep2
  • ahash v1
    member3
• dep2
  • ahash v1
• dep4
  • dep1
    • ahash v3

Which ahash should we select?

• v3 because we pick the highest
• v2 because it is the highest version among the most shallow
• v1 because I'm in member3 and that is the highest version among the most shallow set of ahash
