Struct ColumnToUnpivot 

#[non_exhaustive]
pub struct ColumnToUnpivot {
    pub column_name: Option<String>,
    pub new_value: Option<String>,
}

Specifies a column to be unpivoted, transforming it from a column into rows with associated values.

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.

column_name: Option<String>

The name of the column to unpivot from the source data.

new_value: Option<String>

The value to assign to this column in the unpivoted result, typically the column name or a descriptive label.

Implementations

impl ColumnToUnpivot

pub fn column_name(&self) -> Option<&str>

The name of the column to unpivot from the source data.

pub fn new_value(&self) -> Option<&str>

The value to assign to this column in the unpivoted result, typically the column name or a descriptive label.

impl ColumnToUnpivot

pub fn builder() -> ColumnToUnpivotBuilder

Creates a new builder-style object to manufacture ColumnToUnpivot.

Trait Implementations

impl Clone for ColumnToUnpivot

fn clone(&self) -> ColumnToUnpivot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ColumnToUnpivot

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

Formats the value using the given formatter.

impl PartialEq for ColumnToUnpivot

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