Since [1.64.0](https://blog.rust-lang.org/2022/09/22/Rust-1.64.0.html), Cargo now supports workspace inheritance, so you can avoid duplicating similar field values between crates while working within a workspace. Workspace inheritance can include things like shared `version` numbers, `repository` URLs, or `rust-version`.
This also helps keep these values in sync between crates when updating them. This makes it easier to handle large workspaces.
File: [ROOT]/Cargo.toml
```toml
[workspace]
members = ["a", "b"]
[workspace.package]
version = "1.2.3"
[workspace.dependencies]
serde = "1.0.145"
anyhow = "1.0.65"
```
File: [ROOT]/a/Cargo.toml
```toml
[package]
name = "a"
# use the package version from [ROOT]/Cargo.toml
version.workspace = true
[dependencies]
# use `serde` version from [ROOT]/Cargo.toml
serde = { workspace = true }
# use `anyhow` version from [ROOT]/Cargo.toml
anyhow.workspace = true
```
