Rust app for Linux or RISC-V targets

Pre-requisites

Build the Rust Docker image

docker build -t rust -f rust.Dockerfile .
docker run --rm -ti  -v $(pwd):/usr/src/vnd-boilerplate -w /usr/src/vnd-boilerplate rust:latest

Building

For RISC-V target

cargo build --release

For Linux aarch64 (Mac M1/M2) target

cargo build --release --target aarch64-unknown-linux-gnu

For Linux x86_64 target

cargo build --release --target x86_64-unknown-linux-gnu

Testing (Linux only)

Tests are ran on native thanks to libspeculos.so.

--test-threads=1 is required because libspeculos.so isn't thread safe.

For Linux aarch64 target

docker run --rm -ti  -v $(pwd):/usr/src/vanadium -w /usr/src/vanadium rust:latest
cd app/rust
cargo test --target aarch64-unknown-linux-gnu -- --test-threads=1

For Linux x86_64 target

docker run --rm -ti  -v $(pwd):/usr/src/vanadium -w /usr/src/vanadium rust:latest
cd app/rust
cargo test --target x86_64-unknown-linux-gnu -- --test-threads=1

Notes

• Find which functions take the most of space with cargo install bloat && cargo bloat --release -n 10
