Examine the idea of authoring libraries in Rust, but exposing their APIs via C signatures. The goal being to provide type and memory safety to existing applications and services via API/ABI compatible drop-in replacements for foundational dependencies without needing to perform complete ecosystem rewrites. Apply this concept to common GNU/Linux userspace libraries, such as libc, libm, libssl/libcrypto, etc. What would the impact be? How practical of a solution is this over leaving things as they are or performing large-scale rewrites in Rust?

Thinking

The user is asking about a specific approach to software safety: writing libraries in Rust for memory and type safety, but exposing them through C-compatible ABIs so they can serve as drop-in replacements for existing C libraries in the GNU/Linux ecosystem. This is a nuanced systems programming question that requires

Here's a Terraform configuration using the oracle/oci provider (version ~> 6.0) that provisions a virtual server in Oracle Cloud Infrastructure (OCI) with the specified requirements:

✅ Terraform Configuration

terraform {
  required_providers {
    oci = {
      source  = "oracle/oci"
      version = "~> 6.0"
