Implementations

impl Map

pub fn new( entries: IndexMap<ValueContainer, ValueContainer, RandomState>, ) -> Self

pub fn is_structural(&self) -> bool

pub fn size(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn get<'a>( &self, key: impl Into<ValueKey<'a>>, ) -> Result<&ValueContainer, KeyNotFoundError>

Gets a value in the map by reference. Returns None if the key is not found.

pub fn has<'a>(&self, key: impl Into<ValueKey<'a>>) -> bool

Checks if the map contains the given key.

pub fn delete<'a>( &mut self, key: impl Into<ValueKey<'a>>, ) -> Result<ValueContainer, MapAccessError>

Removes a key from the map, returning the value if it existed.

pub fn clear(&mut self) -> Result<(), MapAccessError>

Clears all entries in the map, returning an error if the map is not dynamic.

Trait Implementations

impl Clone for Map

fn clone(&self) -> Map

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Map

Formats the value using the given formatter.

impl Default for Map

fn default() -> Self

Returns the “default value” for a type.

Formats the value using the given formatter.

impl<K, V> From<HashMap<K, V>> for Map

where K: Into<ValueContainer>, V: Into<ValueContainer>,

fn from(map: HashMap<K, V>) -> Self

Converts to this type from the input type.

impl<K, V> From<IndexMap<K, V, RandomState>> for Map

where K: Into<ValueContainer>, V: Into<ValueContainer>,

fn from(map: IndexMap<K, V, RandomState>) -> Self

Converts to this type from the input type.

impl From<Map> for CoreValue

fn from(value: Map) -> Self

Converts to this type from the input type.

impl From<Vec<(MapKey, ValueContainer)>> for Map

fn from(vec: Vec<(MapKey, ValueContainer)>) -> Self

Converts to this type from the input type.

impl From<Vec<(String, ValueContainer)>> for Map

fn from(vec: Vec<(String, ValueContainer)>) -> Self

Create a dynamic map from a vector of string keys and value containers.

impl From<Vec<(ValueContainer, ValueContainer)>> for Map

fn from(vec: Vec<(ValueContainer, ValueContainer)>) -> Self

Create a dynamic map from a vector of value containers.

impl<K, V> FromIterator<(K, V)> for Map

where K: Into<ValueContainer>, V: Into<ValueContainer>,

fn from_iter<I: IntoIterator<Item = (K, V)>>(iter: I) -> Self

Creates a value from an iterator.

impl Hash for Map

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> IntoIterator for &'a mut Map

type Item = (BorrowedMapKey<'a>, &'a mut ValueContainer)

The type of the elements being iterated over.

type IntoIter = MapMutIterator<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl IntoIterator for Map

type Item = (MapKey, ValueContainer)

The type of the elements being iterated over.

type IntoIter = IntoMapIterator

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

impl PartialEq for Map

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

fn structural_eq(&self, other: &Self) -> bool

Check if two values are equal, ignoring the type.

impl TryFrom<CoreValue> for Map

type Error = String

The type returned in the event of a conversion error.

fn try_from(value: CoreValue) -> Result<Self, Self::Error>

Performs the conversion.
