This commit adds a new test file 'array-from_fn.rs' to the codegen test suite. The test checks the behavior of std::array::from_fn under different optimization levels: 1. At opt-level=0 (debug build), it verifies that the core::array::Guard is present in the generated code. 2. At opt-level=s (size optimization), it ensures that the Guard is optimized out. This test helps ensure that the compiler correctly optimizes array::from_fn calls in release builds while maintaining safety checks in debug builds.
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).
