Implementations

impl Value

pub fn parse<T>(string: T) -> Self

where T: AsRef<str> + Into<String>,

Parse the given string into a Value.

First, it is attempted to parse the string into one of Values non-string types. If each of those attempts fails, a Value::String is returned.

In comparison, the From<&str> and From<String> implementations will always return Value::String.

pub const fn is_string(&self) -> bool

Returns true if the value is a String.

pub const fn as_string(&self) -> Option<&String>

Returns Some if the value is a String.

pub const fn is_number(&self) -> bool

Returns true if the value is a Number.

pub const fn as_number(&self) -> Option<&Number>

Returns Some if the value is a Number.

pub const fn is_bool(&self) -> bool

Returns true if the value is a bool.

pub const fn as_bool(&self) -> Option<bool>

Returns Some if the value is a bool.

Trait Implementations

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<'de> Deserialize<'de> for Value

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

Deserialize this value from the given Serde deserializer.

impl Display for Value

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

Formats the value using the given formatter.

impl From<&str> for Value

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<Box<str>> for Value

fn from(value: Box<str>) -> Self

Converts to this type from the input type.

impl From<Cow<'_, str>> for Value

fn from(value: Cow<'_, str>) -> Self

Converts to this type from the input type.

impl From<Number> for Value

fn from(value: Number) -> Self

Converts to this type from the input type.

impl From<String> for Value

fn from(value: String) -> Self

Converts to this type from the input type.

impl From<Value> for String

fn from(value: Value) -> Self

Converts to this type from the input type.

impl From<bool> for Value

fn from(value: bool) -> Self

Converts to this type from the input type.

impl From<f64> for Value

fn from(value: f64) -> Self

Converts to this type from the input type.

impl From<i64> for Value

fn from(value: i64) -> Self

Converts to this type from the input type.

impl From<u64> for Value

fn from(value: u64) -> Self

Converts to this type from the input type.

impl PartialEq for Value

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

type Error = TryFromValueError

The type returned in the event of a conversion error.

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

Performs the conversion.
