i am running in vscode rust devcontainer (based on mcr.microsoft.com/devcontainers/rust:1-1-bullseye)

i have the following structure (Note: the target and Cargo.lock do not exist until after i attempt a cargo build:

My toml looks like this:

[package]
name = "aipg_client"
version = "0.1.0"
edition = "2021"

[dependencies]
tokio-postgres = "0.7.10"

when i do Cargo build or run from command line, i see this:

vscode ➜ /workspaces/aipg_client $ cargo build

i checked these folders and they are all r/w.
