cargo tree not showing a package

[xphoniex]

Problem

In my Cargo.lock, there is a package called bitvec (and the workspace depends on two versions of it):

[[package]]
name = "parity-scale-codec"
version = "3.2.1"
source = "registry+https://github.com/rust-lang/crates.io-index"
checksum = "366e44391a8af4cfd6002ef6ba072bae071a96aafca98d7d448a34c5dca38b6a"
dependencies = [
 "arrayvec 0.7.2",
 "bitvec 1.0.1",
 "byte-slice-cast",
 "impl-trait-for-tuples",
 "parity-scale-codec-derive",
 "serde",
]

But when I run cargo tree even with extra stuff like --workspace --no-dedupe --all-features:

│   ├── ethabi v18.0.0
...
│   │   │   │   │   └── parity-scale-codec v3.2.1
│   │   │   │   │       ├── arrayvec v0.7.2
│   │   │   │   │       ├── byte-slice-cast v1.2.2
│   │   │   │   │       ├── impl-trait-for-tuples v0.2.2 (proc-macro)
...
│   │   │   │   │       ├── parity-scale-codec-derive v3.1.3 (proc-macro)
...
│   │   │   │   │       └── serde v1.0.148 (*)

where is bitvec 1.0.1 ?

It's hard to say without knowing all the dependencies you have, but I would suspect it is #10801. When there is a weak dependency (like bitvec?/std), the dependency resolver has to assume that bitvec might be enabled. There is a separate pass that then does feature resolution, which may decide that in the end it isn't enabled. But the lock file is built based on the first pass (the dependency resolver).

Without more information, I'm going to close assuming this is #10801. Another possibility is that the dependency is only used on a particular platform. By default cargo tree only shows dependencies for the host target (--target all can be used to show all platforms).

If it looks like it might be something else, feel free to reopen if you can provide a reproduction that we could look at.

You can clone this repo currently @ e7f2637, and:

$ cat Cargo.lock | grep bitvec
name = "bitvec"
name = "bitvec"
 "bitvec 0.19.6",
 "bitvec 1.0.1",

but

$ cargo tree --workspace --no-dedupe --all-features | grep bitvec
│   │   ├── bitvec v0.19.6

[ehuss]

Indeed parity-scale-codec has a feature with bitvec?/std, but nothing enables it. So I think it is #10801.

Thanks for clarification.
