警告

• 待实现。

|see_cpython_module| python:struct.

Supported size/byte order prefixes: @, <, >, !.

Supported format codes: b, B, h, H, i, I, l, L, q, Q, s, P, f, d (the latter 2 depending on the floating-point support).

Functions

ustruct.calcsize(fmt)

Return the number of bytes needed to store the given fmt.

ustruct.pack(fmt, v1, v2, ...)

Pack the values v1, v2, … according to the format string fmt. The return value is a bytes object encoding the values.

ustruct.pack_into(fmt, buffer, offset, v1, v2, ...)

Pack the values v1, v2, … according to the format string fmt into a buffer starting at offset. offset may be negative to count from the end of buffer.

ustruct.unpack(fmt, data)

Unpack from the data according to the format string fmt. The return value is a tuple of the unpacked values.

ustruct.unpack_from(fmt, data, offset=0, /)

Unpack from the data starting at offset according to the format string fmt. offset may be negative to count from the end of buffer. The return value is a tuple of the unpacked values.
