Method Summary
	`__init__(self, value, width, max_num, endian, format, signed, full_range, fuzzable, name)` The bit field primitive represents a number of variable length and is used to define all other integer types.
	`add_integer_boundaries(self, integer)` Add the supplied integer and border cases to the integer fuzz heuristics library.
	`render(self)` Render the primitive.
String	`to_binary(self, number, bit_count)` Convert a number to a binary string.
Integer	`to_decimal(self, binary)` Convert a binary string to a decimal number.
Inherited from base_primitive
Integer	`exhaust(self)` Exhaust the possible mutations for this primitive.
Boolean	`mutate(self)` Mutate the primitive by stepping through the fuzz library, return False on completion.
Integer	`num_mutations(self)` Calculate and return the total number of mutations for this individual primitive.
	`reset(self)` Reset this primitive to the starting mutation state.

	`__delattr__(...)` x.__delattr__('name') <==> del x.name
	`__getattribute__(...)` x.__getattribute__('name') <==> x.name
	`__hash__(x)` x.__hash__() <==> hash(x)
	`__new__(T, S, ...)` T.__new__(S, ...) -> a new object with type S, a subtype of T
	`__reduce__(...)` helper for pickle
	`__reduce_ex__(...)` helper for pickle
	`__repr__(x)` x.__repr__() <==> repr(x)
	`__setattr__(...)` x.__setattr__('name', value) <==> x.name = value

Method Details

The bit field primitive represents a number of variable length and is used to define all other integer types.

Parameters:: value - Default integer value
(type=Integer); width - Width of bit fields
(type=Integer); endian - (Optional, def=LITTLE_ENDIAN) Endianess of the bit field (LITTLE_ENDIAN: <, BIG_ENDIAN: >)
(type=Character); format - (Optional, def=binary) Output format, "binary" or "ascii"
(type=String); signed - (Optional, def=False) Make size signed vs. unsigned (applicable only with format="ascii")
(type=Boolean); full_range - (Optional, def=False) If enabled the field mutates through *all* possible values.
(type=Boolean); fuzzable - (Optional, def=True) Enable/disable fuzzing of this primitive
(type=Boolean); name - (Optional, def=None) Specifying a name gives you direct access to a primitive
(type=String)

Add the supplied integer and border cases to the integer fuzz heuristics library.

Render the primitive.

Convert a number to a binary string.

Parameters:: number - (Optional, def=self.value) Number to convert
(type=Integer); bit_count - (Optional, def=self.width) Width of bit string
(type=Integer)

Convert a binary string to a decimal number.
