Struct Scalar 

pub struct Scalar(/* private fields */);

One plain value in an entry: a boolean, a number, a short text or an enum variant. Nested values are never stored.

Implementations

impl Scalar

pub fn from_json(value: &Value) -> Option<Scalar>

A plain JSON value, text cut to MAX_SCALAR_CHARS. None for arrays and objects, and for null.

pub fn text(text: &str) -> Scalar

Text cut to MAX_SCALAR_CHARS, without control characters.

pub fn of<T>(value: &T) -> Option<Scalar>

where T: Serialize + ?Sized,

Any serializable plain value (a bool, a number, a unit enum, a string). None when it serializes to anything else.

pub fn as_json(&self) -> &Value

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

pub fn as_str(&self) -> Option<&str>

pub fn as_f64(&self) -> Option<f64>

Trait Implementations

impl Clone for Scalar

fn clone(&self) -> Scalar

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Scalar

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Scalar

fn deserialize<__D>( __deserializer: __D, ) -> Result<Scalar, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&str> for Scalar

fn from(value: &str) -> Scalar

Converts to this type from the input type.

impl From<bool> for Scalar

fn from(value: bool) -> Scalar

Converts to this type from the input type.

impl From<i64> for Scalar

fn from(value: i64) -> Scalar

Converts to this type from the input type.

impl PartialEq for Scalar

fn eq(&self, other: &Scalar) -> 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 Serialize for Scalar

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.
