Expand description

Construct a BitVec out of a literal array in source code, like vec!.

bitvec! can be invoked in a number of ways. It takes the name of an Cursor implementation, the name of a Bits-implementing primitive, and zero or more primitives (integer, floating-point, or bool) which are used to build the bits. Each primitive literal corresponds to one bit, and is considered to represent 1 if it is any other value than exactly zero.

bitvec! can be invoked with no specifiers, a Cursor specifier, or a Cursor and a Bits specifier. It cannot be invoked with a Bits specifier but no Cursor specifier, due to overlap in how those tokens are matched by the macro system.

Like vec!, bitvec! supports bit lists [0, 1, …] and repetition markers [1; n].
