ustruct – Pack and Unpack Primitive Data Types
See Python struct for more information.
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.
