Struct EntropyState 

pub struct EntropyState {
    pub value_counts: HashMap<String, u64>,
    pub total_count: u64,
    pub truncated: bool,
}

State for the entropy analyzer.

Fields

value_counts: HashMap<String, u64>

Count of occurrences for each unique value.

total_count: u64

Total count of non-null values.

truncated: bool

Whether the unique value limit was exceeded.

Implementations
