Struct bonsaidb::core::schema::Map

pub struct Map<K = (), V = ()>where
    K: for<'a> Key<'a>,{
    pub source: Header,
    pub key: K,
    pub value: V,
}

A document’s entry in a View’s mappings.

Fields

source: Header

The header of the document that emitted this entry.

key: K

The key used to index the View.

value: V

An associated value stored in the view.

Implementations

impl<K, V> Map<K, V>where
    K: for<'a> Key<'a>,

pub fn new(source: Header, key: K, value: V) -> Map<K, V>

Creates a new Map entry for the document with id source.

Trait Implementations

impl<K, V> Debug for Map<K, V>where
    K: Debug + for<'a> Key<'a>,
    V: Debug,

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

Formats the value using the given formatter.

impl<K, V> Extend<Map<K, V>> for Mappings<K, V>where
    K: for<'a> Key<'a>,

fn extend<T>(&mut self, iter: T)where
    T: IntoIterator<Item = Map<K, V>>,

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

🔬This is a nightly-only experimental API. (extend_one)

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

🔬This is a nightly-only experimental API. (extend_one)

Reserves capacity in a collection for the given number of additional elements.

impl<K, V> FromIterator<Map<K, V>> for Mappings<K, V>where
    K: for<'a> Key<'a>,

fn from_iter<T>(iter: T) -> Mappings<K, V>where
    T: IntoIterator<Item = Map<K, V>>,

Creates a value from an iterator.

impl<K, V> PartialEq<Map<K, V>> for Map<K, V>where
    K: PartialEq<K> + for<'a> Key<'a>,
    V: PartialEq<V>,

fn eq(&self, other: &Map<K, V>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<K, V> StructuralPartialEq for Map<K, V>where
    K: for<'a> Key<'a>,
