SparseArray stores values at sorted, nonnegative indices. Its zero value is an empty array. Constructors and functional updates own their entry slices; copies of reference-bearing T values remain shallow.

## Members

- `Get` (method): Get returns the value at index and reports whether it is present. A missing index, including a sparse hole, returns the zero value and false.
- `Len` (method): Len returns the number of present entries, not the highest index.
- `Indices` (method): Indices returns a fresh slice of present indices in ascending order.
- `Entries` (method): Entries returns a fresh shallow copy in ascending index order.
- `Values` (method): Values returns a fresh shallow slice in ascending index order.
- `All` (method): All returns an iterator over indices and values in ascending index order.
- `With` (method): With returns a copy with value inserted or replaced at index. It leaves the receiver unchanged and returns an error matching [ErrInvalidSparseIndex] for a negative index.
- `Append` (method): Append returns a copy with value stored after the highest present index. It leaves the receiver unchanged and returns an error matching [ErrInvalidSparseIndex] when that index overflows.
