Method append_options

arrow-array/src/builder/generic_bytes_dictionary_builder.rs:373–378

Append an `Option` value into the builder repeatedly `count` times. This is the same as `append_option` but allows to append the same value multiple times without doing multiple lookups. # Panics Panics if the resulting length of the dictionary values array would exceed `T::Native::MAX`

(&mut self, value: Option<impl AsRef<T::Native>>, count: usize)
