调研方向

No file or test is named. Start by reading the ArrayBase and Dim APIs around the existing get operation, then determine where a coordinate bounds predicate belongs. Done means Array2 and Array3 coordinates can be checked without accessing an element, with tests covering in-bounds and out-of-bounds coordinates.

描述

enhancement good first issue

I find myself very frequently having a coordinate and an ndarray Array2/Array3. I want to check whether the coordinate is within the bounds of the Array2/Array3 (IE, gte than 0,0,0, less than the array size). There doesn't appear to be a way to do this. There is "get" to return a value or None but that is not the same thing. Sometimes I want to know if the value is inbounds without, at that time, accessing the value.

It would be helpful to add a within(), contains() etc function to ArrayBase (I think adding it to Dim would also serve equivalent purposes).

(If this already exists and I just missed it, sorry)
