pvm-rust

The Polkadot Virtual Machine (PVM) in Rust, implemented from the JAM Gray Paper. Jamixir, an Elixir JAM client, runs it through a Rustler NIF. The crate itself has no Elixir dependency.

Layout

• core: memory, registers, program and bitmask handling
• encoding: program blob decoding (deblob) and encoding
• init: program initialisation and memory layout
• vm: instruction dispatch, single-step execution, gas, child instances, tracing
• execution: entry points for disassembled and linked programs

Tests

git clone https://github.com/jamixir/jamtestvectors ../pvm-test-vectors
cargo test

The unit tests need nothing else. The vectors suite reads the PVM test vectors from ../pvm-test-vectors/pvm/programs/.
