Struct gremlin_client::Map

pub struct Map(_);

Represent a Map<GKey,GValue> which has ability to allow for non-String keys. TinkerPop type here

Methods

impl Map

pub fn iter(&self) -> impl Iterator<Item = (&GKey, &GValue)>

Iterate all key-value pairs

pub fn get<T>(&self, key: T) -> Option<&GValue> where
    T: Into<GKey>, 

Returns a reference to the value corresponding to the key.

pub fn len(&self) -> usize

Returns the number of elements in the map.

pub fn is_empty(&self) -> bool

Returns true if the map contains no elements.

Trait Implementations

impl PartialEq<Map> for Map

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

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

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

This method tests for !=.

impl Clone for Map

fn clone(&self) -> Map

Returns a copy of the value.

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

Performs copy-assignment from source.

impl From<HashMap<GKey, GValue, RandomState>> for Map

fn from(val: HashMap<GKey, GValue>) -> Self

Performs the conversion.

impl From<HashMap<String, GValue, RandomState>> for Map

fn from(val: HashMap<String, GValue>) -> Self

Performs the conversion.

impl From<BTreeMap<String, GValue>> for Map

fn from(val: BTreeMap<String, GValue>) -> Self

Performs the conversion.

impl Debug for Map

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

Formats the value using the given formatter.

impl<T: Into<GKey>> Index<T> for Map

type Output = GValue

The returned type after indexing.

fn index(&self, key: T) -> &GValue

Performs the indexing (container[index]) operation.

impl FromIterator<(String, GValue)> for Map

fn from_iter<I: IntoIterator<Item = (String, GValue)>>(iter: I) -> Self

Creates a value from an iterator.
