Module utils

Utilities for performing commonly used algorithms in Starknet.

Structs

NonAsciiNameError

The string provided contains non-ASCII characters.

UdcUniqueSettings

The uniqueness settings when using UdcUniqueness::Unique for contract deployment.

Enums

CairoShortStringToFeltError

Possible errors for encoding a Cairo short string.

ParseCairoShortStringError

Possible errors for decoding a Cairo short string.

UdcUniqueness

The uniqueness settings for UDC deployments.

Functions

cairo_short_string_to_felt

Converts Cairo short string to Felt.

get_contract_address

Computes the target contract address of a “native” contract deployment. Use get_udc_deployed_address instead if you want to compute the target address for deployments through the Universal Deployer Contract.

get_selector_from_name

Calculates the entrypoint selector from a human-readable function name.

get_storage_var_address

Calculates the standard storage slot address of storage variable in a Cairo contract.

get_udc_deployed_address

Computes the target contract address for deployments through the Universal Deploy Contract.

normalize_address

Normalizes an address to be in the range of [0, 2^251 - 256).

parse_cairo_short_string

Converts Felt to Cairo short string.

starknet_keccak

A variant of eth-keccak that computes a value that fits in a Starknet field element. It performs a standard Keccak-256 but with the 6 most significant bits removed.
