class dsviper.Type¶

Bases: object

A utility class to handle type representation.

Note: Not directly instantiable.

ANY_CONCEPT = any_concept¶

BLOB = blob¶

BLOB_ID = blob_id¶

BOOL = bool¶

COMMIT_ID = commit_id¶

DOUBLE = double¶

FLOAT = float¶

INT16 = int16¶

INT32 = int32¶

INT64 = int64¶

INT8 = int8¶

STRING = string¶

UINT16 = uint16¶

UINT32 = uint32¶

UINT64 = uint64¶

UINT8 = uint8¶

UUID = uuid¶

VOID = void¶

static decode(blob: ValueBlob, definitions: DefinitionsConst, *, stream_codec_instancing: StreamCodecInstancing | None = None) → Type¶: Return a type by decoding the blob with a StreamBinaryCodec if not specified.

static encode(type: Type, *, stream_codec_instancing: StreamCodecInstancing | None = None) → ValueBlob¶: Return a blob that encodes the type with a StreamBinaryCodec if not specified.

static hexdigest(type: Type, *, hashing: Hashing | None = None) → str¶: Return the hexa digest of the type computed with the hashing interface if specified else use SHA1.

static is_sized(type: Type) → bool¶: Return True if the type has a fixed size.

static read(stream_reading: StreamReading, definitions: DefinitionsConst) → Type¶: Read and return a type.

static size_of(type: Type, stream_sizing: StreamSizing) → int¶: Return the fixed size of the type or raise.

static use_blob_id(type: Type) → bool¶: Return True if the type uses the type blob_id.

static write(type: Type, stream_writing: StreamWriting) → None¶: Write a type.
