Method new_unchecked

arrow-data/src/data.rs:288–315

Create a new ArrayData instance; If `null_count` is not specified, the number of nulls in null_bit_buffer is calculated. If the number of nulls is 0 then the null_bit_buffer is set to `None`. # Safety The input values *must* form a valid Arrow array for `data_type`, or undefined behavior can result. Note: This is a low level API and most users of the arrow crate should create arrays using the
