Variants

Null

Bool(bool)

Int(i64)

Float(f64)

String(String)

DateTime(String)

An RFC 3339 date-time, e.g. 2026-06-12T09:30:00Z. Construct with Value::datetime to get format validation.

StringArray(Vec<String>)

IntArray(Vec<i64>)

FloatArray(Vec<f64>)

Json(Value)

Implementations

impl Value

pub fn datetime(value: impl Into<String>) -> Result<Value, GrustError>

Creates a Value::DateTime, validating that the input is an RFC 3339 date-time such as 2026-06-12T09:30:00Z or 2026-06-12T09:30:00.123+02:00.

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

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

pub fn as_string_array(&self) -> Option<&[String]>

pub fn as_int_array(&self) -> Option<&[i64]>

pub fn as_float_array(&self) -> Option<&[f64]>

pub fn to_json(&self) -> Value

Converts to a plain (untagged) JSON value. DateTime becomes a JSON string, so a to_json/from_json round trip yields Value::String.

pub fn from_json(value: Value) -> Value

Converts from JSON, accepting both plain values and the tagged {"type": ..., "value": ...} form that Value’s serde representation produces.

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a duplicate 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<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Value

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&String> for Value

fn from(value: &String) -> Value

Converts to this type from the input type.

impl From<&str> for Value

fn from(value: &str) -> Value

Converts to this type from the input type.

impl From<String> for Value

fn from(value: String) -> Value

Converts to this type from the input type.

impl From<Value> for Value

fn from(value: Value) -> Value

Converts to this type from the input type.

impl From<Vec<String>> for Value

fn from(value: Vec<String>) -> Value

Converts to this type from the input type.

impl From<Vec<f64>> for Value

fn from(value: Vec<f64>) -> Value

Converts to this type from the input type.

impl From<Vec<i64>> for Value

fn from(value: Vec<i64>) -> Value

Converts to this type from the input type.

impl From<bool> for Value

fn from(value: bool) -> Value

Converts to this type from the input type.

impl From<f64> for Value

fn from(value: f64) -> Value

Converts to this type from the input type.

impl From<i32> for Value

fn from(value: i32) -> Value

Converts to this type from the input type.

impl From<i64> for Value

fn from(value: i64) -> Value

Converts to this type from the input type.

impl From<usize> for Value

fn from(value: usize) -> Value

Converts to this type from the input type.

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.

impl Serialize for Value

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.
