Struct ColumnChange 

pub struct ColumnChange {
    pub name: String,
    pub value: Value,
    /* private fields */
}

One column of a change, retaining its original parent generations privately.

Fields

name: String

The column name.

value: Value

The value an insert or update writes, or the cell a delete removes. Value::Null is SQL NULL. An update shows no value it replaced.

Implementations

impl ColumnChange

pub fn new(name: impl Into<String>, value: Value) -> ColumnChange

A column the conversion adds; it carries no references.

Trait Implementations

impl Clone for ColumnChange

fn clone(&self) -> ColumnChange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ColumnChange

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

Formats the value using the given formatter.

impl PartialEq for ColumnChange

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