[PR] build-env: introduce env for building std ta. [incubator-teaclave-trustzone-sdk]
m4sterchain opened a new pull request, #207:
URL: https://github.com/apache/incubator-teaclave-trustzone-sdk/pull/207
# Add Standard Library Development Support
Introduces comprehensive support for Rust standard library (std) development alongside the existing no-std environment.
## Key Features
- **Flexible configuration management** - Dynamic switching between std/no-std modes and architectures via `switch_config`
- **Std-enabled Docker environment** - New development image with Rust std support
- **Mixed development workflow** - Support for different host and TA architectures in same project
- **Comprehensive documentation** - New guide covering std-specific differences and capabilities
## Changes
- Add std development documentation guide (`docs/emulate-and-dev-in-docker-std.md`)
- Implement `switch_config` tool for runtime configuration management
- Add std-enabled Docker environment with setup scripts
- Update configuration system to support std/no-std switching
- Enhance hello-world example to demonstrate std vs no-std builds
## Benefits
- Enables use of std-dependent crates (collections, networking, serialization)
- Streamlines development workflow with unified environment
- Maintains backward compatibility with existing no-std development
- Provides clear migration path between development modes

Review Comment:
The title is a bit confusing to me. Iād prefer something like "Developing std TAs with Docker" or another you think fits better.

+# š Standard Library Development with Docker
+
+This guide covers the **key differences** when developing with **Rust standard library (std) support**
+compared to the regular no-std environment documented in [emulate-and-dev-in-docker.md](emulate-and-dev-in-docker.md).
+
+> š **Prerequisites**: Read the [original Docker development guide](emulate-and-dev-in-docker.md)
+> first. This document focuses only on std-specific differences and capabilities.
+
+## What's Different with Std Development
+
+The std-enabled environment adds:
+- **Flexible configuration management** - Switch between std/no-std modes and architectures dynamically
+- **Rust standard library tailored for OP-TEE** - Collections, networking, serialization capabilities
+- **Mixed development support** - Combine different host and TA architectures in the same project
Review Comment:
Is **Mixed development support** specific to std? I think it's shared design.

Review Comment:
Both. You can also update the original `no-std` doc, to illustrate switching between no-std archs using the new config system.
