Struct Node 

pub struct Node {
    pub length: u64,
    pub null_count: u64,
}

One array in a batch, in the flattened order the schema puts them in.

This is the same pair Arrow IPC calls a field node, and it is here for the same reason: a column’s length and null count are not derivable from its buffers, so somebody has to say them out loud.

Fields

length: u64

How many slots the array has.

null_count: u64

How many of those slots are null.

Implementations

impl Node

pub const SIZE: usize = 16

How wide the encoded form is, in bytes.
