Trait Implementations

impl Arbitrary for Value

type Parameters = ()

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = BoxedStrategy<Value>

The type of Strategy used to generate values of type Self.

fn arbitrary_with(_: Self::Parameters) -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl Clone for Value

fn clone(&self) -> Value

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl Default for Value

fn default() -> Value

Returns the “default value” for a type.

impl From<&str> for Value

fn from(v: &str) -> Self

Converts to this type from the input type.

impl From<Bin> for Value

fn from(v: Bin) -> Self

Converts to this type from the input type.

impl From<Ext> for Value

fn from(v: Ext) -> Self

Converts to this type from the input type.

impl From<Int> for Value

fn from(v: Int) -> Self

Converts to this type from the input type.

impl From<Str> for Value

fn from(v: Str) -> Self

Converts to this type from the input type.

impl From<String> for Value

fn from(v: String) -> Self

Converts to this type from the input type.

impl From<Vec<(Value, Value)>> for Value

fn from(v: Vec<(Value, Value)>) -> Self

Converts to this type from the input type.

impl From<Vec<Value>> for Value

fn from(v: Vec<Value>) -> Self

Converts to this type from the input type.

impl From<bool> for Value

fn from(v: bool) -> Self

Converts to this type from the input type.

impl From<f32> for Value

fn from(v: f32) -> Self

Converts to this type from the input type.

impl From<f64> for Value

fn from(v: f64) -> Self

Converts to this type from the input type.

impl From<i16> for Value

fn from(v: i16) -> Self

Converts to this type from the input type.

impl From<i32> for Value

fn from(v: i32) -> Self

Converts to this type from the input type.

impl From<i64> for Value

fn from(v: i64) -> Self

Converts to this type from the input type.

impl From<i8> for Value

fn from(v: i8) -> Self

Converts to this type from the input type.

impl From<isize> for Value

fn from(v: isize) -> Self

Converts to this type from the input type.

impl From<u16> for Value

fn from(v: u16) -> Self

Converts to this type from the input type.

impl From<u32> for Value

fn from(v: u32) -> Self

Converts to this type from the input type.

impl From<u64> for Value

fn from(v: u64) -> Self

Converts to this type from the input type.

impl From<u8> for Value

fn from(v: u8) -> Self

Converts to this type from the input type.

impl From<usize> for Value

fn from(v: usize) -> Self

Converts to this type from the input type.

impl<T> Index<T> for Value

where T: Index,

fn index(&self, index: T) -> &Self::Output

Accessing inner values of value using indexing value[0] or value["foo"].

Panics

This function panics when self does not contain given key.

Duplicate keys

If self is a map object and contains two or more keys matching against the given index, indexing works as if the preceding keys do not exist in the object. This is the same behaviour as what EMCA-262 specifies.

let v = msgpack!({ "a" : 0, "a" : 1 });
assert_eq!(v["a"], Int::from(1u32).into());

type Output = Value

The returned type after indexing.

impl PartialEq for Value

fn eq(&self, other: &Value) -> 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.

type Error = TryFromValueError

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

Performs the conversion.

impl TryFrom<Value> for Vec<(Value, Value)>
