Trait Implementations

impl Clone for Mapping

fn clone(&self) -> Mapping

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Mapping

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

Formats the value using the given formatter.

impl Default for Mapping

fn default() -> Mapping

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Mapping

fn deserialize<D>( deserializer: D, ) -> Result<Mapping, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Extend<(Value, Value)> for Mapping

fn extend<I>(&mut self, iter: I)

where I: IntoIterator<Item = (Value, Value)>,

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 From<Mapping> for Value

fn from(f: Mapping) -> Value

Convert map (with string keys) to Value

Examples

use serde_yaml::{Mapping, Value};

let mut m = Mapping::new();
m.insert("Lorem".into(), "ipsum".into());
let x: Value = m.into();

impl FromIterator<(Value, Value)> for Mapping

fn from_iter<I>(iter: I) -> Mapping

where I: IntoIterator<Item = (Value, Value)>,

Creates a value from an iterator.

impl Hash for Mapping

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

where __H: Hasher,

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> Index<&'a Value> for Mapping

type Output = Value

The returned type after indexing.

fn index(&self, index: &'a Value) -> &Value

Performs the indexing (container[index]) operation.

impl<'a> IndexMut<&'a Value> for Mapping

fn index_mut(&mut self, index: &'a Value) -> &mut Value

Performs the mutable indexing (container[index]) operation.

impl<'a> IntoIterator for &'a Mapping

type Item = (&'a Value, &'a Value)

The type of the elements being iterated over.

type IntoIter = Iter<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> <&'a Mapping as IntoIterator>::IntoIter

Creates an iterator from a value.

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

type Item = (&'a Value, &'a mut Value)

The type of the elements being iterated over.

type IntoIter = IterMut<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> <&'a mut Mapping as IntoIterator>::IntoIter

Creates an iterator from a value.

impl IntoIterator for Mapping

type Item = (Value, Value)

The type of the elements being iterated over.

type IntoIter = IntoIter

Which kind of iterator are we turning this into?

fn into_iter(self) -> <Mapping as IntoIterator>::IntoIter

Creates an iterator from a value.

impl PartialEq for Mapping

fn eq(&self, other: &Mapping) -> 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 PartialOrd for Mapping

fn partial_cmp(&self, other: &Mapping) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Mapping

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
