Struct ValueChange 

#[non_exhaustive]
pub struct ValueChange {
    pub old: CellValue,
    pub new: CellValue,
    pub reason: ValueDifferenceKind,
}

A value-layer change at one cell address.

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.

old: CellValue

new: CellValue

reason: ValueDifferenceKind

Trait Implementations

impl Clone for ValueChange

fn clone(&self) -> ValueChange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValueChange

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

Formats the value using the given formatter.

impl PartialEq for ValueChange

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