zserio.bitsizeof module

The module provides help methods to calculate size of nontrivial types.

zserio.bitsizeof.bitsizeof_bitbuffer(bitbuffer: BitBuffer) → int

Gets the bit size of bit buffer which is stored in bit stream.

Parameters:

bitbuffer – Bit buffer for calculation.

Returns:

Length of bit buffer in bits.

Raises:

PythonRuntimeException – Throws if given bit buffer is too long.

zserio.bitsizeof.bitsizeof_bytes(value: bytearray) → int

Gets bit size of bytes.

Parameters:

value – Bytes value to use for bit size calculation.

Raises:

PythonRuntimeException – Throws if given string is too long.

zserio.bitsizeof.bitsizeof_string(string: str) → int

Gets bit size of string.

Parameters:

string – String value to use for bit size calculation.

Raises:

PythonRuntimeException – Throws if given string is too long.

zserio.bitsizeof.bitsizeof_varint(value: int) → int

Gets bit size of variable signed integer value (up to 9 bytes).

Parameters:

value – Value to use for bit size calculation.

Returns:

Bit size of the value.

Raises:

PythonRuntimeException – Throws if given value is out of range for varint type.

zserio.bitsizeof.bitsizeof_varint16(value: int) → int

Gets bit size of variable 16-bit signed integer value.

Parameters:

value – Value to use for bit size calculation.

Returns:

Bit size of the value.

Raises:

PythonRuntimeException – Throws if given value is out of range for varint16 type.

zserio.bitsizeof.bitsizeof_varint32(value: int) → int

Gets bit size of variable 32-bit signed integer value.

Parameters:

value – Value to use for bit size calculation.

Returns:

Bit size of the value.

Raises:

PythonRuntimeException – Throws if given value is out of range for varint32 type.

zserio.bitsizeof.bitsizeof_varint64(value: int) → int

Gets bit size of variable 64-bit signed integer value.

Parameters:

value – Value to use for bit size calculation.

Returns:

Bit size of the value.

Raises:

PythonRuntimeException – Throws if given value is out of range for varint64 type.

zserio.bitsizeof.bitsizeof_varsize(value: int) → int

Gets bit size of variable size integer value.

Parameters:

value – Value to use for bit size calculation.

Returns:

Bit size of the value.

Raises:

PythonRuntimeException – Throws if given value is out of range for varsize type.

zserio.bitsizeof.bitsizeof_varuint(value: int) → int

Gets bit size of variable unsigned integer value (up to 9 bytes).

Parameters:

value – Value to use for bit size calculation.

Returns:

Bit size of the value.

Raises:

PythonRuntimeException – Throws if given value is out of range for varuint type.

zserio.bitsizeof.bitsizeof_varuint16(value: int) → int

Gets bit size of variable 16-bit unsigned integer value.

Parameters:

value – Value to use for bit size calculation.

Returns:

Bit size of the value.

Raises:

PythonRuntimeException – Throws if given value is out of range for varuint16 type.

zserio.bitsizeof.bitsizeof_varuint32(value: int) → int

Gets bit size of variable 32-bit unsigned integer value.

Parameters:

value – Value to use for bit size calculation.

Returns:

Bit size of the value.

Raises:

PythonRuntimeException – Throws if given value is out of range for varuint32 type.

zserio.bitsizeof.bitsizeof_varuint64(value: int) → int

Gets bit size of variable 64-bit unsigned integer value.

Parameters:

value – Value to use for bit size calculation.

Returns:

Bit size of the value.

Raises:

PythonRuntimeException – Throws if given value is out of range for varuint64 type.
