URL: https://github.com/apache/teaclave-trustzone-sdk/pull/309
This PR reorganizes the examples into dedicated CA and TA Cargo workspaces
and consolidates shared protocol definitions into a single proto crate.
## Benefits
### Faster and more resource-efficient CI
The workspace layout allows examples to reuse compiled dependencies
instead of rebuilding them for each individual example.
As a result:
- Overall CI time decreased from 24 minutes to 10 minutes
- CA build artifacts use 736 MB
- TA build artifacts use 1.6 GB
- Build artifacts are reused throughout CI and cleaned after the complete
build
### More idiomatic Rust project structure
The new layout follows standard Rust workspace conventions:
- CA and TA crates are managed by separate workspaces
- Protocol definitions are organized as modules in one shared proto crate
- Common build logic is centralized in workspace-specific Makefile includes
- Workspace-level dependency resolution and lock files reduce duplicated
configuration
This is especially useful for examples containing multiple TAs. Each TA
can be represented as an independent workspace member while sharing
dependencies, protocol types, build
configuration, and artifacts naturally through Cargo.
### Better inter-TA communication
The consolidated proto crate also improves inter-TA calls. A TA can
directly import another TA’s UUID and command definitions from the
corresponding protocol module.
This removes the need to hard-code another TA’s UUID or duplicate its
command IDs in the caller. Consequently:
- UUIDs and commands have a single source of truth
- Inter-TA callers and callees cannot silently drift apart
- Adding or changing commands is safer and easier to maintain
- Multi-TA dependencies are explicit in Rust code
For example:
use proto::hello_world::{Command, UUID};
## New Layout
examples/
├── ca/
│ ├── Cargo.toml
│ ├── Makefile.include
│ └── <CA crates>
└── ta/
├── Cargo.toml
├── Makefile.include
├── proto/
└── <TA crates>
The resulting organization is faster to build, easier to maintain, safer
for inter-TA communication, and better aligned with Rust conventions.
