Enum Value 

pub enum Value {
    Null,
    Bool(bool),
    UInt(u64),
    Int(i64),
    Float(f64),
    Str(String),
    Bytes(Vec<u8>),
    Array(Vec<Value>),
    Object(Vec<(String, Value)>),
}

Owned, schema-less Crous value (analogous to serde_json::Value).

This type owns all its data and can be freely moved, cloned, and serialized.

Variants

Null

Null / absent value.

Bool(bool)

Boolean.

UInt(u64)

Unsigned integer (up to u64).

Int(i64)

Signed integer (i64).

Float(f64)

64-bit IEEE 754 float.

Str(String)

UTF-8 string.

Bytes(Vec<u8>)

Raw binary blob.

Array(Vec<Value>)

Ordered array of values.

Object(Vec<(String, Value)>)

Ordered map of key-value pairs (keys are strings). Uses Vec to preserve insertion order (deterministic encoding).

Implementations

impl Value

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

Returns the type name as a human-readable string.

pub fn is_null(&self) -> bool

Returns true if this value is null.

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

Try to get as a string reference.

pub fn as_uint(&self) -> Option<u64>

Try to get as u64.

pub fn as_int(&self) -> Option<i64>

Try to get as i64.

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

Try to get as f64.

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

Try to get as a boolean.

pub fn as_array(&self) -> Option<&[Value]>

Try to get as an array.

pub fn as_object(&self) -> Option<&[(String, Value)]>

Try to get as an object (ordered key-value pairs).

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

Formats the value using the given formatter.

impl Display for Value

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

Formats the value using the given formatter.

impl From<&Value> for Value

Convert from serde_json::Value to crous Value for interop.

fn from(jv: &Value) -> Self

Converts to this type from the input type.

impl From<&Value> for Value

Convert from crous Value to serde_json::Value for interop.

fn from(cv: &Value) -> Self

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.
