Standardize version management across multi-crate Rust projects by using workspace versioning. This reduces duplication and ensures consistency across all crates in your project. Implementation: 1. Define the version once in the workspace Cargo.toml: ```toml [workspace] version = "0.1.0" ``` 2. Reference this version in each crate's Cargo.toml: ```toml [package] name = "your-crate-name" version = { workspace = true } ``` This approach centralizes version management, making it easier to release coordinated updates across all crates while maintaining a consistent configuration structure.
