Write an array to a const context.

Makes the array, array reference, or array slice available for import into the main crate via use_symbols. Stack allocated types (such as slices and arrays) may be returned.

Parameters

• $id: the name/identifier to give the exported array
• $t: the type of elements of the exported array will contain. Optionally followed by : DIM where DIM is the dimension (1, 2, 3, …) of the array. The dimension defaults to 1 when unspecified.
• $data: the contents of the array. May be an array, an array reference, or array slice.

Further notes

• Must be called from a build script (build.rs) only.
• If the array is large and referenced many times, this will lead to code bloat. In such a case, consider carefully whether write_static_array would be more appropriate instead.
