Implementations

impl WireValue

pub fn null() -> Self

Create a null value

pub fn is_null(&self) -> bool

Check if this value is null

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

Try to get this value as a number

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

Try to get this value as a string

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

Try to get this value as a boolean

pub fn type_name(&self) -> &'static str

Get the type name for display purposes

Trait Implementations

impl Clone for WireValue

fn clone(&self) -> WireValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WireValue

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for WireValue

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&Value> for WireValue

fn from(json: &Value) -> Self

Converts to this type from the input type.

impl From<&str> for WireValue

fn from(s: &str) -> Self

Converts to this type from the input type.

impl<T: Into<WireValue>> From<Option<T>> for WireValue

fn from(opt: Option<T>) -> Self

Converts to this type from the input type.

impl From<String> for WireValue

fn from(s: String) -> Self

Converts to this type from the input type.

impl From<Value> for WireValue

Convert from serde_json::Value to WireValue

This allows creating envelopes from JSON values for display purposes. Note: This conversion is lossy - JSON doesn’t have type information for things like Timestamp vs Integer, so we use heuristics.

fn from(json: Value) -> Self

Converts to this type from the input type.

impl<T: Into<WireValue>> From<Vec<T>> for WireValue

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

Converts to this type from the input type.

impl From<bool> for WireValue

fn from(b: bool) -> Self

Converts to this type from the input type.

impl From<f32> for WireValue

fn from(n: f32) -> Self

Converts to this type from the input type.

impl From<f64> for WireValue

fn from(n: f64) -> Self

Converts to this type from the input type.

impl From<i16> for WireValue

fn from(n: i16) -> Self

Converts to this type from the input type.

impl From<i32> for WireValue

fn from(n: i32) -> Self

Converts to this type from the input type.

impl From<i64> for WireValue

fn from(n: i64) -> Self

Converts to this type from the input type.

impl From<i8> for WireValue

fn from(n: i8) -> Self

Converts to this type from the input type.

impl From<u16> for WireValue

fn from(n: u16) -> Self

Converts to this type from the input type.

impl From<u32> for WireValue

fn from(n: u32) -> Self

Converts to this type from the input type.

impl From<u64> for WireValue

fn from(n: u64) -> Self

Converts to this type from the input type.

impl From<u8> for WireValue

fn from(n: u8) -> Self

Converts to this type from the input type.

impl PartialEq for WireValue

fn eq(&self, other: &WireValue) -> 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 WireValue

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
