Run Rust utilities server-side with WASI and Wasmtime: portable, sandboxed modules without container weight.
An architecture note on using WebAssembly bulk memory instructions (memory.fill, memory.copy, memory.init) for fast, safe data movement across module boundaries, covering requirements, minimal design, trust boundaries, operational checks, failure modes, and when to reconsider the approach.
Goal: Configure a repeatable WASI host environment for a Wasmtime development container that exposes a fixed set of preopened directories and environment variables to a WASM module. WASI snapshot_01 standardizes file descriptors through preopened directories but does not standardize TCP/UDP sockets, so outbound network access depends on runtime-specific exte
