This is an opinionated way to start a rust project

Initialise a rust project in the current folder

cargo init

This is how cargo.toml looks like initially. cargo.toml - This is called a manifest, and it contains all of the metadata that Cargo needs to compile your package.

[package]
name = "rust-base"
version = "0.1.0"
edition = "2021"

[dependencies]

Dependencies to add First we add thiserror for error handling under dependencies

thiserror = "1"

If you intend to use async add tokio

tokio = { version = "1", features = ["full"] }

If you are doing a command line interface you may use

clap = { version = "4", features = ["cargo"] }

Add dev dependencies anyhow - good for unit tests, examples and benchmarks

[dev-dependencies]
anyhow = "1"

[package]
name = "rust-base"
version = "0.1.0"
edition = "2021"

[dependencies]
tokio = { version = "1", features = ["full"] }

[dev-dependencies]
anyhow = "1"

Now run

cargo build

Then

cargo run

Or

./target/debug/rust-base
