Expand descriptionA multi-dimensional array.
Implementations§
Creates a new Array from its underlying components.
The data array should be provided in the higher-dimensional equivalent
of row-major order.
§Panics
Panics if the number of elements provided does not match the number of
elements specified by the dimensions.
Creates a new one-dimensional array.
Wraps this array in a new dimension of size 1.
For example, the one dimensional array [1, 2] would turn into the
two-dimensional array [[1, 2]].
Consumes another array, appending it to the top level dimension of this
array.
The dimensions of the other array must be the same as the dimensions
of this array with the first dimension removed. This includes lower
bounds as well as lengths.
For example, if [3, 4] is pushed onto [[1, 2]], the result is
[[1, 2], [3, 4]].
§Panics
Panics if the dimensions of the two arrays do not match.
Returns the dimensions of this array.
Returns an iterator over references to the elements of the array in the
higher-dimensional equivalent of row-major order.
Returns an iterator over mutable references to the elements of the
array in the higher-dimensional equivalent of row-major order.
Returns the underlying data vector for this Array in the
higher-dimensional equivalent of row-major order.

A convenience function that delegates to from_sql and from_sql_null depending on the
value of raw. Source§Indexes into the Array, retrieving a reference to the contained
value.
Since Arrays can be multi-dimensional, the Index trait is
implemented for a variety of index types. In the most generic case, a
&[i32] can be used. In addition, a bare i32 as well as tuples
of up to 10 i32 values may be used for convenience.
§Panics
Panics if the index does not correspond to an in-bounds element of the
Array.
§Examples
let mut array = Array::from_vec(vec![0i32, 1, 2, 3], 0);
assert_eq!(2, array[2]);
array.wrap(0);
array.push(Array::from_vec(vec![4, 5, 6, 7], 0));
assert_eq!(6, array[(1, 2)]);
