smallpond.execution.task.JobId

class smallpond.execution.task.JobId(hex=None, bytes=None, bytes_le=None, fields=None, int=None, version=None, *, is_safe=SafeUUID.unknown)

A unique identifier for a job.

__init__(hex=None, bytes=None, bytes_le=None, fields=None, int=None, version=None, *, is_safe=SafeUUID.unknown)

Create a UUID from either a string of 32 hexadecimal digits, a string of 16 bytes as the ‘bytes’ argument, a string of 16 bytes in little-endian order as the ‘bytes_le’ argument, a tuple of six integers (32-bit time_low, 16-bit time_mid, 16-bit time_hi_version, 8-bit clock_seq_hi_variant, 8-bit clock_seq_low, 48-bit node) as the ‘fields’ argument, or a single 128-bit integer as the ‘int’ argument. When a string of hex digits is given, curly braces, hyphens, and a URN prefix are all optional. For example, these expressions all yield the same UUID:

UUID(‘{12345678-1234-5678-1234-567812345678}’) UUID(‘12345678123456781234567812345678’) UUID(’urn:uuid:12345678-1234-5678-1234-567812345678’) UUID(bytes=’x12x34x56x78’*4) UUID(bytes_le=’x78x56x34x12x34x12x78x56’ +

‘x12x34x56x78x12x34x56x78’)

UUID(fields=(0x12345678, 0x1234, 0x5678, 0x12, 0x34, 0x567812345678)) UUID(int=0x12345678123456781234567812345678)

Exactly one of ‘hex’, ‘bytes’, ‘bytes_le’, ‘fields’, or ‘int’ must be given. The ‘version’ argument is optional; if given, the resulting UUID will have its variant and version set according to RFC 4122, overriding the given ‘hex’, ‘bytes’, ‘bytes_le’, ‘fields’, or ‘int’.

is_safe is an enum exposed as an attribute on the instance. It indicates whether the UUID has been generated in a way that is safe for multiprocessing applications, via uuid_generate_time_safe(3).

Methods

__init__([hex, bytes, bytes_le, fields, ...])

Create a UUID from either a string of 32 hexadecimal digits, a string of 16 bytes as the 'bytes' argument, a string of 16 bytes in little-endian order as the 'bytes_le' argument, a tuple of six integers (32-bit time_low, 16-bit time_mid, 16-bit time_hi_version, 8-bit clock_seq_hi_variant, 8-bit clock_seq_low, 48-bit node) as the 'fields' argument, or a single 128-bit integer as the 'int' argument.
