app-rust

Rust app for the RISC-V target

Pre-requisites

Some libraries are required to build a Rust app:

• libc.a to build the app for the RISC-V target
• libcrypto.a to pass tests on the x64 target

These libraries can be retrieved from Docker images thanks to the script lib/create-lib.sh:

./lib/create-lib.sh

They are also generated as artifacts by the GitHub CI.

Build

cargo build --release

Tests

cargo test --target x86_64-unknown-linux-gnu -- --test-threads=1

Tests are ran on x64 thanks to libspeculos.so.

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

Notes

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