in my rust project, i run cargo vendor and vendored all dependencies in vendor folder. The .cargo/config.toml file is updated to point to vendor/ folder.
[source.vendored-sources]
directory = "vendor"
Some of the vendored crates i have patched, so they are moved from vendor to patch folder, and Cargo.toml is updated as
[patch.crates-io]
patched-crate = {path = "patch/patched-crate"}
All builds fine, and runs fine.
I use nvim + rust-analyser, with appropriate plugins. When i open a file from patched crate, rust-analyzer complains that it cannot read metadata of the patched crate.
It also gives a solution that it can be fixed by adding the patched crate to the workspace in Cargo.toml
LSP[rust_analyzer] rust-analyzer failed to load workspace: Failed to read Cargo metadata from Cargo.toml file /home/vimalkum/src/vector-collector/vector/patch/hyper-openssl/Cargo.toml, cargo 1.58.0 (f01b232bc 2022-01-19): Failed to run `

t package believes it's in a workspace when it's not:
current: /home/vimalkum/src/vector-collector/vector/patch/hyper-openssl/Cargo.toml
workspace: /home/vimalkum/src/vector-collector/vector/Cargo.toml
this may be fixable by adding `patch/hyper-openssl` to the `workspace.members` array of the manifest located at: /home/vimalkum/src/vector-collector/vector/Cargo.toml
Alternatively, to keep it out of the workspace, add the package to the `workspace.exclude` array, or add an empty `[workspace]` table to the package's manifest.
When i add the patched crate to workspace
[workspace]
members = [
".",
"lib/crate1",
"lib/crate2",
"patch/*",
"vendor/*".
]
i get build errors that it cannot load manifest of the vendored crate
cargo build --release --no-default-features --features ocp-logging
error: failed to load manifest for workspace member `/home/vimalkum/src/vector-collector/vector/vendor/azure_storage`
Edit 1
As suggested in a comment, I updated Cargo.toml with only the patch directories. And when i open in it nvim, i get error
LSP[rust_analyzer] rust-analyzer failed to load workspace: Failed to read Cargo metadata from Cargo.toml file /home/vimalkum/src/vector-collector/vector/Cargo.toml, cargo 1.58.0 (f01b232bc 2022-01-19): Failed to run `"cargo" "metadata" "

`hyper-rustls = "^0.23.0"`
candidate versions found which didn't match: 0.22.1
location searched: directory source `/home/vimalkum/src/vector-collector/vector/vendor` (which is replacing registry `crates-io`)
required by package `aws-config v0.9.0 (/home/vimalkum/src/vector-collector/vector/patch/aws-config)`
perhaps a crate was updated and forgotten to be re-vendored?
but vendor folder contains hyper-rustls version version = "0.22.1"
