Struct MapDiff 

pub struct MapDiff<T> {
    pub insert: HashMap<String, T>,
    pub remove: HashSet<String>,
}

Rules for updating a Map.

Fields

insert: HashMap<String, T>

Values to insert/replace into Map::map.

remove: HashSet<String>

Values to remove from Map::map.

Implementations

impl<T> MapDiff<T>

pub fn apply_once(self, to: &mut Map<T>)

Applies the diff.

If you want to apply self multiple times, use Self::apply_multiple as it’s slightly faster than Clone::cloneing this then using Self::apply_once on each clone.

impl<T: Clone> MapDiff<T>

pub fn apply_multiple(&self, to: &mut Map<T>)

Applies the diff.

If you only want to apply self once, use Self::apply_once.

Trait Implementations

impl<T: Clone> Clone for MapDiff<T>

fn clone(&self) -> MapDiff<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for MapDiff<T>

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

Formats the value using the given formatter.

impl<T: Default> Default for MapDiff<T>

fn default() -> MapDiff<T>

Returns the “default value” for a type.

impl<'de, T> Deserialize<'de> for MapDiff<T>

where T: Deserialize<'de> + Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T: PartialEq> PartialEq for MapDiff<T>

fn eq(&self, other: &MapDiff<T>) -> 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<T> Serialize for MapDiff<T>

where T: Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
