Does features in [dependencies] in the Cargo.toml will be enabled by RA?

[huang-jl]

The following toml settings is part of a rust project. Note that it specify the features in the vm-memory dependency.

[package]
name = "vmm"
version = "0.1.0"
authors = ["Amazon Firecracker team <firecracker-devel@amazon.com>"]
edition = "2021"
license = "Apache-2.0"

[dependencies]
vm-memory = { version = "0.13.1", features = ["backend-mmap", "backend-bitmap"] }

I have set the rust-analyzer.cargo.features to default value (i.e. []) and DO NOT enable allFeatures.

When I edit the .rs source code files in the project directory, everything works fine, and the RA seems to recognize the features in Cargo.toml, i.e., it enables the "backend-mmap" and "backend-bitmap".

But when I jump into the source code files in the dependency crate (e.g., files in ~/.cargo/registry/src/......), which is outside the project directory, the RA DO NOT enable "backend-mmap" and "backend-bitmap". RA seems use the rust-analyzer.cargo.features for those files outside the project directory, instead of using that in [dependencies] section in Cargo.toml.

My questions are:

1. Why features in [dependencies] not enable when I jump into source code in the dependency crate? Is there something I missed?
2. Because I do not want to enable all features in the dependencies (which means I do not want to enable rust-analyzer.cargo.allFeatures), how can RA only enables the features in the [dependencies] section in Cargo.toml when I jump into the source code files in that crate?
