Aliased Type

pub struct FA {
    pub field: Arc<Field>,
    pub array: Array,
    pub null_count: usize,
}

Fields

field: Arc<Field>

Array metadata

array: Array

The array’s inner payload is wrapped in Arc for immutability so it can safely share across threads. When part of a Table (or higher-dimensional structure), immutability also upholds shape constraints.

null_count: usize

Null count for the immutable array to support skipping null-mask operations when it’s 0, and/or related strategies.
