Functions ¶

func PrecomputeAddress ¶ added in v0.7.1

func PrecomputeAddress(deployerAddress *felt.Felt, salt *felt.Felt, classHash *felt.Felt, constructorCalldata []*felt.Felt) *felt.Felt

PrecomputeAddress calculates the precomputed address for a contract instance. ref: https://github.com/starkware-libs/cairo-lang/blob/master/src/starkware/starknet/core/os/contract_address/contract_address.py

Parameters:

deployerAddress: the deployer address
salt: the salt
classHash: the class hash
constructorCalldata: the constructor calldata

Returns:

*felt.Felt: the precomputed address as a *felt.Felt

Types ¶

type CasmClass ¶ added in v0.4.6

type CasmClass struct {
	Prime                  string                     `json:"prime"`
	Version                string                     `json:"compiler_version"`
	ByteCode               []*felt.Felt               `json:"bytecode"`
	EntryPointByType       CasmClassEntryPointsByType `json:"entry_points_by_type"`
	BytecodeSegmentLengths *NestedUints               `json:"bytecode_segment_lengths,omitempty"`
}

func UnmarshalCasmClass ¶ added in v0.4.6

func UnmarshalCasmClass(filePath string) (*CasmClass, error)

UnmarshalCasmClass is a function that unmarshals a CasmClass object from a file. CASM = Cairo instructions

It takes a file path as a parameter and returns a pointer to the unmarshaled CasmClass object and an error.

type CasmClassEntryPoint ¶ added in v0.4.6

type CasmClassEntryPoint struct {
	Selector *felt.Felt `json:"selector"`
	Offset   int        `json:"offset"`
	Builtins []string   `json:"builtins"`
}

type CasmClassEntryPointsByType ¶ added in v0.4.6

type CasmClassEntryPointsByType struct {
	Constructor []CasmClassEntryPoint `json:"CONSTRUCTOR"`
	External    []CasmClassEntryPoint `json:"EXTERNAL"`
	L1Handler   []CasmClassEntryPoint `json:"L1_HANDLER"`
}

type NestedUints ¶ added in v0.8.0

type NestedUints struct {
	IsArray bool
	Value   *uint64
	Values  []NestedUints
}

func (NestedUints) MarshalJSON ¶ added in v0.8.0

func (ns NestedUints) MarshalJSON() ([]byte, error)

MarshalJSON implements the json.Marshaler interface for NestedUints. It converts the NestedUints structure back into a JSON array format.

func (*NestedUints) UnmarshalJSON ¶ added in v0.8.0

func (ns *NestedUints) UnmarshalJSON(data []byte) error
