OCF Basic Syntax

The basic syntax of the func part in OCF uses the Rust programming language(version 1.76.0). Rust is a powerful language, but we have temporarily restricted some of its advanced syntax elements to ensure swift and secure experimentation.

Currently, we have imposed the following limitations on OCF:

• OCF func is stateless and does not support deployers' custom variable definitions. Although the CVM has a system state, OCF deployers cannot define new states.

• OCF func can only contain one statement, supporting the use of system functions and operators to form this statement.

• OCF func doesn't support loops, structs, enums, pattern matching, Crates, collections, error handling, traits, closures, etc.

The above restrictions will gradually be relaxed to unleash Rust's full potential.

Developers' func code is deployed in the CVM, a WASM-based virtual machine implemented by Compos Protocol. We plan to open-source the entire project soon.
