Struct FieldAnalysis 

pub struct FieldAnalysis {
    pub name: String,
    pub field_type: String,
    pub null_count: usize,
    pub unique_count: Option<usize>,
}

Analysis of a field across an array of objects.

Used by StatsResult to provide insights into consistent fields in arrays of objects, including type information and null counts.

Fields

name: String

Field name (key)

field_type: String

Most common type for this field

null_count: usize

Number of objects where this field is null

unique_count: Option<usize>

Number of distinct values (omitted for high-cardinality fields)
