// Fork 5 of 20 Parent id
|
|
//
|
|
// The leading 0s are important. In the above example, you only need 3 bits to
|
|
// represent slot 5. However, you need 5 bits to represent all the forks at
|
|
// the current level, so we must account for the empty bits at the end.
|
|
//
|
|
// For this same reason, slots are 1-indexed instead of 0-indexed. Otherwise,
|
|
// the zeroth id at a level would be indistinguishable from its parent.
|
|
//
|
|
// If a node has only one child, and does not materialize an id (i.e. does not
|
|
// contain a useId hook), then we don't need to allocate any space in the
|
|
// sequence. It's treated as a transparent indirection. For example, these two
|
|
// trees produce the same ids:
|
|
//
|
|
// <> <>
|
|
// <Indirection> <A />
|
|
// <A /> <B />
|
|
// </Indirection> </>
|
|
// <B />
|
|
// </>
|
|
//
|
|
// However, we cannot skip any node that materializes an id. Otherwise, a parent
|
|
// id that does not fork would be indistinguishable from its child id. For
|
|
// example, this tree does not fork, but the parent and child must have
|
|
// different ids.
|
|
//
|
|
// <Parent>
|
|
// <Child />
|
|
// </Parent>
|
|
//
|
|
// To handle this scenario, every time we materialize an id, we allocate a
|
|
// new level with a single slot. You can think of this as a fork with only one
|
|
// prong, or an array of children with length 1.
|
|
//
|
|
// It's possible for the size of the sequence to exceed 32 bits, the max
|
|
// size for bitwise operations. When this happens, we make more room by
|
|
// converting the right part of the id to a string and storing it in an overflow
|
|
// variable. We use a base 32 string representation, because 32 is the largest
|
|
// power of 2 that is supported by toString(). We want the base to be large so
|
|
// that the resulting ids are compact, and we want the base to be a power of 2
|
|
// because every log2(base) bits corresponds to a single character, i.e. every
|
|
// log2(32) = 5 bits. That means we can lop bits off the end 5 at a time without
|
|
// affecting the final result.
