Option to show semver constraints in cargo tree #16163
Description
Problem
cargo tree currently produces the following output:
test1 v0.1.0 (/home/user/test1)
|-- clap v4.5.50
| `-- clap_builder v4.5.50
| |-- anstream v0.6.21
`-- toml v0.9.8
|-- anstream v0.6.21 (*)
This lacks information about the version constraint that the dependency had to satisfy to be resolved.
Proposed Solution
Adding a flag to cargo tree that produces version constraint information, where enabling it would produce different output:
test1 v0.1.0 (/home/user/test1)
-|-- clap v4.5.50
+|-- clap v4.5.50 satisfies ^4.5.50
-| `-- clap_builder v4.5.50
+| `-- clap_builder v4.5.50 satisfies =4.5.50
-| |-- anstream v0.6.21
+| |-- anstream v0.6.21 satisfies ^0.6.7
-`-- toml v0.9.8
+`-- toml v0.9.8 satisfies ^0.9.8
- |-- anstream v0.6.21 (*)
+ |-- anstream v0.6.21 (*) satisfies ^0.6.20Instead of adding an explicit flag, this could be also provided as a new format-string {v} or {c} such that
$ cargo tree --format "{p} satisfies {c}"would produce the same output
Notes
The provided example is derived from the following manifest and lockfile:
