Struct MapDiff 

pub struct MapDiff<K, V> {
    pub added: Vec<Added<(K, V)>>,
    pub removed: Vec<Removed<(K, V)>>,
    pub updated: Vec<Updated<K, V>>,
    pub unchanged: Vec<Unchanged<(K, V)>>,
}

Deterministic structural diff for a map collection.

Fields

added: Vec<Added<(K, V)>>

Entries added in stable key order.

removed: Vec<Removed<(K, V)>>

Entries removed in stable key order.

updated: Vec<Updated<K, V>>

Entries updated in stable key order.

unchanged: Vec<Unchanged<(K, V)>>

Entries retained in stable key order.

Implementations

impl<K, V> MapDiff<K, V>

where K: Clone + Ord, V: Clone + PartialEq,

pub fn is_empty(&self) -> bool

Returns true when the diff has no structural changes.

Trait Implementations

impl<K: Clone, V: Clone> Clone for MapDiff<K, V>

fn clone(&self) -> MapDiff<K, V>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<K: Debug, V: Debug> Debug for MapDiff<K, V>

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

Formats the value using the given formatter.

impl<K: Eq, V: Eq> Eq for MapDiff<K, V>

impl<K: PartialEq, V: PartialEq> PartialEq for MapDiff<K, V>

fn eq(&self, other: &MapDiff<K, V>) -> 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.
