This crate provides a jagged array, i.e. a type that is semantically equivalent to
Box<[Box<[T]>]>
, but implemented with better memory locality and fewer heap allocations.
Example
extern crate jagged_array;
extern crate streaming_iterator;
use FromIterator;
use Jagged2;
use StreamingIterator;
// Create a jagged array from a vector of vectors
let mut a = from_iter;
// indexing is done in (row, column) form and supports `get` and `get_mut` variants.
assert_eq!;
*a.get_mut.unwrap = 11;
assert_eq!;
// Whole rows can also be accessed and modified
assert_eq!;
a.get_row_mut.unwrap = 11;
// Note that although elements are modifiable, the structure is not;
// items cannot be inserted into rows, nor can new rows be added.
// Iteration via `StreamingIterator`s. See the docs for more detail.
let mut iter = a.stream;
while let Some = iter.next
