Crate leo_ast

The abstract syntax tree (ast) for a Leo program.

This module contains the Ast type, a wrapper around the Program type. The Ast type is intended to be parsed and modified by different passes of the Leo compiler. The Leo compiler can generate a set of R1CS constraints from any Ast.

Modules

• access
• common
• expressions
• functions
• groups
• mapping
• passes
  This module contains both a Reducer and Visitor design pattern. These both iterate over the AST.
• program
  A Leo program consists of import statements and program scopes.
• statement
• struct

  A stub contains function templates as well as definitions for mappings, structs, records, and constants.
• types
• value

Macros

• simple_node_impl

Structs

• Ast
  The abstract syntax tree (AST) for a Leo program.

Functions

• normalize_json_value
  Helper function to normalize AST JSON into a form compatible with tgc. This function will traverse the original JSON value and produce a new one under the following rules:
• remove_key_from_json
  Helper function to recursively filter keys from AST JSON
