RHEL 8 provides Rust Toolset in version 1.92.0 RHEL 8 is distributed with Rust Toolset in version 1.92.0. Notable enhancements since the previously available version 1.88.0 include: * Reliable Debugging: Unwind tables are now emitted by default on Linux even when compiling with -Cpanic=abort, ensuring backtraces work correctly for debugging. * Systems Programming: i128/u128 types are now fully supported in extern "C" functions, and developers can now create raw pointers to union fields using &raw in safe code. * Enhanced Safety: The new dangling_pointers_from_locals lint now warns against returning dangling raw pointers derived from local variables. * Code Clarity: A new mismatched_lifetime_syntaxes lint warns when lifetime elision rules hide potentially confusing relationships between input and output lifetimes. * Workflow Improvements: Cargo now natively supports workspace publishing via cargo publish --workspace, automatically handling dependency ordering for multi-crate projects. Rust Toolset is a rolling Application Stream, and Red Hat only supports the latest version.
