Rholang Runtime

A rholang runtime written in Rust. Development is still in progress...

• /model/ is a library crate containing protobuf models depended by rho_runtime and rholang_parser
• /rholang_parser/ crate builds an executable program which accepts rholang code and outputs normalized AST
• /rho_runtime/ is the primary executable program. It launches rholang_parser to parse rholang code, then handle reducing and storage

File Naming Convertion

Two kinds of naming convertions applied in this project.

• Filename using snake_case (e.g. common.rs / rho_par.rs) means it is an individual module, which is the default approach in Rust's module system.
• Filename using PascalCase (e.g. Sortable.rs / DeBruijnIndexMap.rs) means it is a part of its directory module.

The PascalCase style is used to keep the code structure similar as Scala edition without big single file or a lot of re-exports.

src/
├─ context/
│  ├─ mod.rs
│  ├─ DeBruijnLevelMap.rs
│  ├─ DeBruijnIndexMap.rs
├─ normalize/
│  ├─ mod.rs
│  ├─ rho_par.rs

In the above example, DeBruijnLevelMap.rs and DeBruijnIndexMap.rs are included by /src/context/mod.rd as part of context module; While rho_par.rs defines normalize::rho_par module.
