Trait Accessor

pub trait Accessor<T>: Send + Sync {
    // Required methods
    fn array_len(&self) -> usize;
    fn is_valid(&self, index: usize) -> bool;
    fn value_unchecked(&self, index: usize) -> T;
    fn array_validity(&self) -> Validity;

    // Provided methods
    fn batch_size(&self, start_idx: usize) -> usize { ... }
    fn decode_batch(&self, start_idx: usize) -> Vec<T> { ... }
