Bootstrap: Don't get output if `lldb --version` errors fixes #126892 `Command` can error in two ways: the OS can fail to run the binary at all or else the binary can return an error exit code. Unfortunately the distinction between the two is not clear cut. The OS may succeed in starting the binary but it may still error before `main` (e.g. if a necessary library fails to load) and this will be reported via the exit code. Fortunately this case is simpler. We can assume that `lldb --version` will only ever error if there's a startup issue of some kind. so both kinds of errors are caused by the OS. Thus it's safe for us to treat them equally for the sake of this specific check. |

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrate with other languages.
-
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
-
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
