Features

• default — Default features: std, utilizes faster-hex for hexadecimal operations and enables bytes standard features.
• std (enabled by default) — Default features: std, utilizes faster-hex for hexadecimal operations and enables bytes standard features.
• bytes_vec - Introduced in version 0.8, the 0.8 molecule defaults to bytes, which has implications for use in the CKB runtime. The bytes_vec feature provides users with a compatibility option to maintain consistency with previous versions.

Use in CKB scripts

When used in CKB scripts, no-std needs to be specified.

molecule = { version = "0.7", default-features = false }

Particularly, for versions later than 0.8, you need to additionally specify the bytes_vec feature.

molecule = { version = "0.8.0", default-features = false, features = ["bytes_vec"] }

Tools

Schema Compiler and Code Generator

Install

The official schema compiler and code generator are written in Rust, so you can install it via Cargo:

cargo install moleculec --locked

Note: the official code generator is only support two languages: Rust and C.

Usage

• You can use the follow command to generate the code:

  moleculec --language <language> --schema-file <schema-file>
  

• More details can be found by the follow command:

  moleculec --help

Molecule's reference implementation is in Rust and C.

Implementations in other languages are maintained by respective authors.

• Go
• Modern JavaScript

Plugins for Editors

• Emacs
• Vim
• Sublime Text
