cargo-geiger 命令

常用示例

说明

cargo-geiger is a Cargo subcommand that scans a Rust project's dependency tree to detect and report usage of unsafe Rust code. It counts unsafe expressions, function declarations, trait implementations, and method calls in both the project and all its dependencies. The output shows a tree view of the dependency graph annotated with counts of unsafe code usage, helping developers assess the safety profile of their dependency chain. Crates using `#!forbid(unsafe_code)` are clearly marked as verified safe. The name is a reference to a Geiger counter, which detects radiation — similarly, cargo-geiger detects potentially dangerous unsafe code.
