[GitHub] [arrow-rs] alippai opened a new issue #352: Shortcut for utf8 bytes append

alippai opened a new issue #352:
URL: https://github.com/apache/arrow-rs/issues/352


   **Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
   I want to append utf8 bytes from a trusted source to a `GenericStringBuilder` directly.
   
   **Describe the solution you'd like**
   I'd add a `fn append_slice(&mut self, value: &[u8])` helper function to the GenericStringBuilder struct.
   
   **Describe alternatives you've considered**
   Currently this is a workaround:
   `use arrow::array::GenericStringBuilder.append_value(std::str::from_utf8_unchecked(my_bytes))`
