Goish: พอร์ตรันไทม์ของ Go ทั้งตัวลงใน no_std Rust

Goish is a Rust runtime for Go programmers that aims to provide a single binary static executable with all the features of Go 1.25. It ports the standard library and runtime of Go to Rust, without relying on any external libraries or the Rust standard library, including no_std, glibc, std, Tokio, and garbage collection. The project was inspired by the need to port Go code to Rust due to memory safety concerns or corporate policies.

Goish achieves this by porting Go code line-by-line and then refactoring modules into Rust idioms as the team becomes more comfortable. It includes a memory allocator and 67 size classes, but no garbage collector. Rust ownership is used to reclaim memory instead of a garbage collector. The scheduler is a verbatim port of the Go runtime/proc.go, using a lock-free Per-P run queue, work stealing, async preemption through SIGURG, and a per-P sysmon for timer management.

The crypto/tls package is fully ported with 100% coverage and includes all 1722 declarations. The result is a single binary static executable, reducing the attack surface to just the binary itself, making it suitable for scratch/distribeless containers, confidential VMs, and appliance images.
