pub(crate) struct BddPointer(pub(crate) u32);
Expand description

(internal) A type-safe index into the Bdd node array representation.

BDD pointers are an internal type-safe wrapper around indices into BDD arrays. Outside this crate, no one should know or care about their existence. Since we can’t reasonably expect a BDD to be larger than 2^32 right now, the pointer is represented as u32 instead of usize, because usize can be 64-bits and pointers represent most of the memory consumed by our BDDs.

Tuple Fields

0: u32

Implementations

Make a new pointer to the 0 terminal node.

Make a new pointer to the 1 terminal node.

Check if the pointer corresponds to the 0 terminal.

Check if the pointer corresponds to the 1 terminal.

Check if the pointer corresponds to the 0 or 1 terminal.

Cast this pointer to standard usize index.

Create a pointer from an usize index.

Convert a bool value to valid terminal BDD pointer.

If this pointer is a terminal, convert it to bool, otherwise return None.

If this pointer corresponds to a terminal node, flip it (switching 1 to 0 and vice versa).

Convert to little endian bytes

Read from little endian byte representation
