jam.types.protocol.service module

class jam.types.protocol.service.ServiceInfo(code_hash: ByteArray32, balance: U64, min_item_gas: U64, min_memo_gas: U64, bytes_data: U64, items: U32)[source]

Bases: Codable, JsonSerde

Service information structure.

code_hash: ByteArray32

balance: U64

min_item_gas: U64

min_memo_gas: U64

bytes_data: U64

items: U32

__init__(code_hash: ByteArray32, balance: U64, min_item_gas: U64, min_memo_gas: U64, bytes_data: U64, items: U32) → None

Initialize the Codable.

Parameters:

codec – Optional codec to use for encoding/decoding
enc_sequence – Optional function that returns sequence of fields to encode

static decode_from(buffer: bytes | bytearray | memoryview, offset: int = 0) → Tuple[T, int]

Decode from buffer. Must be implemented by subclasses or added via decorator.

Parameters:

buffer – Buffer to decode from
offset – Starting position in buffer

Returns:

The decoded value
Number of bytes read

Return type:

Tuple containing

encode_into(buffer: bytearray, offset: int = 0) → int: Encode into provided buffer.

encode_size() → int: Calculate number of bytes needed to encode.
