Struct SkewedInfo 

#[non_exhaustive]
pub struct SkewedInfo {
    pub skewed_column_names: Option<Vec<String>>,
    pub skewed_column_values: Option<Vec<String>>,
    pub skewed_column_value_location_maps: Option<HashMap<String, String>>,
}

Specifies skewed values in a table. Skewed values are those that occur with very high frequency.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

skewed_column_names: Option<Vec<String>>

A list of names of columns that contain skewed values.

skewed_column_values: Option<Vec<String>>

A list of values that appear so frequently as to be considered skewed.

skewed_column_value_location_maps: Option<HashMap<String, String>>

A mapping of skewed values to the columns that contain them.

Implementations

impl SkewedInfo

pub fn skewed_column_names(&self) -> &[String]

A list of names of columns that contain skewed values.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .skewed_column_names.is_none().

pub fn skewed_column_values(&self) -> &[String]

A list of values that appear so frequently as to be considered skewed.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .skewed_column_values.is_none().

pub fn skewed_column_value_location_maps( &self, ) -> Option<&HashMap<String, String>>

A mapping of skewed values to the columns that contain them.

impl SkewedInfo

pub fn builder() -> SkewedInfoBuilder

Creates a new builder-style object to manufacture SkewedInfo.

Trait Implementations

impl Clone for SkewedInfo

fn clone(&self) -> SkewedInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SkewedInfo

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

Formats the value using the given formatter.

impl PartialEq for SkewedInfo

fn eq(&self, other: &SkewedInfo) -> 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.
