Enum Change 

pub enum Change {
    Equal,
    Delete,
    Insert,
}

The role a line plays in a Diff.

A diff is a sequence of lines, each tagged with how it relates to the two inputs. “Expected” is the baseline (the left/old side); “actual” is the value under test (the right/new side).

Variants

Equal

The line is present, unchanged, in both the expected and actual text.

Delete

The line is present in the expected text but missing from the actual text. Rendered with a leading -.

Insert

The line is present in the actual text but was not expected. Rendered with a leading +.

Implementations

impl Change

pub const fn marker(self) -> char

The single-character marker used when rendering this change in a unified diff: ' ' for Equal, '-' for Delete, '+' for Insert.

Trait Implementations

impl Clone for Change

fn clone(&self) -> Change

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Change

impl Debug for Change

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

Formats the value using the given formatter.

impl Eq for Change

impl Hash for Change

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Change

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