Enums

AbiDecoded

A decoded ABI value, produced by decode_from_abi.

AbiType

ABI type representation for function parameters and return values.

AbiValue

A concrete ABI value used as a function argument or return value.

FunctionType

The type of a contract function.

Functions

abi_checker

Validate a contract artifact’s ABI for correctness.

abi_type_signature

Convert an ABI type to its canonical Noir signature representation.

abi_type_size

Compute the number of field elements an ABI type occupies when flattened.

buffer_as_fields

Split a byte buffer into field elements for on-chain storage.

buffer_from_fields

Reconstruct a byte buffer from field elements produced by buffer_as_fields.

count_arguments_size

Compute the total flattened field-element count for a function’s parameters.

decode_from_abi

Decode field elements back into typed ABI values.

encode_arguments

ABI-encode a function’s arguments into field elements.

encode_value

is_address_struct

Returns true if the ABI type represents an AztecAddress or EthAddress struct.

is_aztec_address_struct

Returns true if the ABI type is an AztecAddress struct.

is_bounded_vec_struct
