Overview

michelson-ast is a Rust library for generating Michelson code. This library can handle the Abstract Syntax Tree (AST) of Michelson, the smart contract language for Tezos.

Usage

To generate Michelson code using this library, you can write a program like the following:

use michelson_ast::{
    instruction::Instruction,
    program::Program, ty::Ty,
    wrapped_instruction::WrappedInstruction,
};

fn main() {
    let program = Program {
        storage: Ty::Unit,
        parameter: Ty::Unit,
        code: vec![
            WrappedInstruction {
                comment: Some("=> Unit".to_owned()),
                instruction: Instruction::Cdr,
            },
            WrappedInstruction {
                comment: Some("=> {} : Unit".to_owned()),
                instruction: Instruction::Nil { ty: Ty::Operation },
            },
            WrappedInstruction {
                comment: Some("=> (Pair {} Unit)".to_owned()),
                instruction: Instruction::Pair,
            },
        ],
    };

    println!("{}", program.to_string());
}

Example output

parameter unit;
storage unit;
code {
       CDR; # => Unit
       NIL operation; # => {} : Unit
       PAIR; # => (Pair {} Unit)
     }
