Source 
pub fn create_binary_array_with_seed<Offset: OffsetSizeTrait>(
    size: usize,
    null_density: f32,
    bytes_seed: u64,
    bytes_length_seed: u64,
) -> GenericBinaryArray<Offset>
Expand description

Creates a random GenericBinaryArray of a given size and null_density filling it with random bytes, generated using the provided seeds.

the bytes_seed is used to seed the RNG for generating the byte values, while the bytes_length_seed is used to seed the RNG for generating the length of an array item

These values can be the same as they are used to seed different RNGs internally.
