Struct Diff

#[non_exhaustive]
pub struct Diff {
    pub insertions: HashSet<usize>,
    pub deletions: HashSet<usize>,
    pub updates: HashSet<usize>,
    pub moves: HashSet<DiffMove>,
}

Represents a diff between two arrays.

Create a diff between arrays of QueryResultItems using a Differ.

Alternatively, you can directly create a Diff via Diff::empty:

let mut diff = Diff::empty();
diff.insertions.extend([1, 2, 3]);

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.

insertions: HashSet<usize>

The set of indexes in the new array at which new items have been inserted.

deletions: HashSet<usize>

The set of indexes in the old array at which old items have been deleted.

updates: HashSet<usize>

The set of indexes in the new array at which items have been updated.

moves: HashSet<DiffMove>

A set of tuples each representing a move of an item from a particular index in the old array to a particular index in the new array.

Implementations

impl Diff

pub fn empty() -> Self

Create a new empty Diff instance.

This is equivalent to calling Diff::default().

Trait Implementations

impl Clone for Diff

fn clone(&self) -> Diff

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Diff

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

Formats the value using the given formatter.

impl Default for Diff

fn default() -> Diff

Returns the “default value” for a type.

impl PartialEq for Diff

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

impl Eq for Diff

impl StructuralPartialEq for Diff
