[GitHub] [arrow-rs] alamb opened a new issue #1202: Add doc examples for `eq_dyn` etc.

alamb opened a new issue #1202:
URL: https://github.com/apache/arrow-rs/issues/1202


   The comparison kernels have a somewhat bewildering array of options for a new developer
   
   https://docs.rs/arrow/7.0.0/arrow/compute/kernels/comparison/index.html
   
   We have been making the API easier to use with so called `dyn` kernels (such as `eq_dyn`, etc) but this may not be as discoverable as would be ideal. 
   
   Thus it would be great to add some doctests to the `comparison` module that demonstrated how to use those kernels with an example of creating two arrays, and then calling `eq_dyn` on them

   Perhaps one could follow the example of
   
   https://docs.rs/arrow/7.0.0/arrow/array/type.StringArray.html
   
   ```rust
   use arrow::array::StringArray;
   let array1 = StringArray::from(vec![Some("foo"), None, Some("bar")]);
   let array2 = StringArray::from(vec![Some("foo"), None, Some("baz")]);
   let result = eq_dyn(&array1, &array2).unwrap();
   assert_eq!(BooleanArray::from(vec![Some(true), None, Some(false)]), result))
   ```
