Traits

ExtractFromPython

Trait for types that can be extracted from Python with improved error messages.

Functions

extract_binary_operands

Generic function for extracting operands from binary operations.

extract_list

Generic function for extracting lists of items with error handling.

extract_operator_type

Generic function for extracting Python operator types with consistent error handling.

extract_optional

Generic function to safely extract optional attributes.

extract_position_info

Generic function to extract position information from AST nodes.

extract_required_attr

Extract a required attribute with enhanced error messaging

extract_with_context

Extract a value from PyAny with better error messaging

extraction_error

Helper function to create standardized error messages for failed extractions.

extraction_failure

Build a PyErr for a failed AST-node conversion, carrying the node’s source position so the error can be reported against the user’s Python code instead of panicking with an internal dump.

get_attr_with_context

Enhanced error handling utilities for parsing Python AST objects Get an attribute from a Python object with better error messaging

log_extraction

Utility function for consistent logging during Python object extraction.

safe_ident

Build an identifier for generated code from a Python name, escaping Rust keywords so identifiers like type, match, or move don’t produce invalid Rust. Keywords that cannot be raw identifiers (self, Self, super, crate) get a trailing underscore instead — except self, which is left as-is so method receivers keep working.
