Struct CategoricalProfile 

pub struct CategoricalProfile {
    pub nrows: usize,
    pub cardinality: usize,
    pub missing: usize,
    pub bytes_used: usize,
    pub avg_byte_len: usize,
    pub max_byte_len: usize,
    pub code_width_bytes: usize,
    pub unique_ratio_thousandths: u64,
}

Internal stats computed by CategoricalColumn::profile(). Integer fields only — no float math, deterministic.

Fields

nrows: usize

cardinality: usize

missing: usize

bytes_used: usize

avg_byte_len: usize

max_byte_len: usize

code_width_bytes: usize

unique_ratio_thousandths: u64

(cardinality / nrows) * 1000 rounded toward zero. Reported in thousandths to keep the profile integer-only.

Trait Implementations

impl Clone for CategoricalProfile

fn clone(&self) -> CategoricalProfile

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CategoricalProfile

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for CategoricalProfile

fn eq(&self, other: &CategoricalProfile) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
