Module stellar_helpers

Helper functions for Stellar-specific operations.

This module provides utility functions for working with Stellar-specific data types and formatting, including address normalization, XDR value parsing, and operation processing.

Enums

StellarType

Represents all possible Stellar smart contract types

StellarValue

Represents all possible Stellar smart contract values

Functions

are_same_address

Compares two Stellar addresses for equality, ignoring case and whitespace.

are_same_signature

Compares two Stellar function signatures for equality, ignoring case and whitespace.

combine_i128

Combines the parts of an Int128 into a single string representation.

combine_i256

Combines the parts of an Int256 into a single string representation. Note: hi_hi is signed (i64) while other components are unsigned (u64)

combine_u128

Combines the parts of a UInt128 into a single string representation.

combine_u256

Combines the parts of a UInt256 into a single string representation.

get_contract_code_ledger_key

Extracts contract code ledger key from a contract’s XDR-encoded executable.

get_contract_instance_ledger_key

Creates a LedgerKey for the contract instance.

get_contract_spec

Parse a WASM contract from hex and return a vector of ScSpecEntry.

get_contract_spec_functions

Get contract spec functions from a contract spec.

get_contract_spec_with_function_input_parameters

Parse contract spec functions and populate input parameters.

get_function_signature

Gets the function signature for a Stellar host function operation.

Get the kind of a value from a JSON value.

get_wasm_code_from_ledger_entry_data

Get WASM code from a contract’s XDR-encoded executable.

get_wasm_hash_from_ledger_entry_data

Get WASM hash from a contract’s XDR-encoded executable.

hex_to_bytes

Convert a hexadecimal string to a byte vector.

is_address

Checks if a string is a valid Stellar address.

normalize_address

Normalizes a Stellar address by removing whitespace and converting to lowercase.

normalize_signature

Normalizes a Stellar function signature by removing whitespace and converting to lowercase.

parse_sc_val

Parses a Stellar Contract Value into a decoded parameter entry.

parse_xdr_value

Parses XDR-encoded bytes into a decoded parameter entry.

process_invoke_host_function

Processes a Stellar host function operation into a parsed result.
