Enum Value 

pub enum Value {
    Nil,
    Bool(bool),
    Int(i64),
    Float(NotNan<f64>),
    Str(String),
    Map(CrdtId),
    Text(CrdtId),
    Set(CrdtId),
    Register(CrdtId),
}

Unified value type for reading from CRDTs.

This enum represents all values that can be read from CRDTs. Primitive variants contain data directly; CRDT variants contain opaque CrdtId handles for navigation.

For writing primitive values, use PrimitiveValue instead — it prevents accidentally passing CRDT references to set().

Variants

Nil

Nil/null value.

Bool(bool)

Boolean value.

Int(i64)

64-bit signed integer.

Float(NotNan<f64>)

64-bit floating point (never NaN).

Str(String)

String value (UTF-8).

Map(CrdtId)

Reference to a nested Map CRDT.

Text(CrdtId)

Reference to a nested Text CRDT.

Set(CrdtId)

Reference to a nested Set CRDT.

Register(CrdtId)

Reference to a nested Register CRDT.

Implementations

impl Value

pub fn is_nil(&self) -> bool

Check if this value is nil.

pub fn is_primitive(&self) -> bool

Check if this value is a primitive (not a CRDT reference).

pub fn is_crdt(&self) -> bool

Check if this value is a CRDT reference.

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

Get as bool if this is a boolean.

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

Get as i64 if this is an integer.

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

Get as f64 if this is a float. Get as f64 if this is a float.

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

Get as str if this is a string.

pub fn crdt_id(&self) -> Option<CrdtId>

Get the CRDT ID if this is a CRDT reference.

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<&str> for Value

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<()> for Value

fn from(_: ()) -> Self

Converts to this type from the input type.

impl From<PrimitiveValue> for Value

fn from(v: PrimitiveValue) -> Self

Converts to this type from the input type.

impl From<String> for Value

fn from(s: String) -> Self

Converts to this type from the input type.

impl From<bool> for Value

fn from(b: bool) -> Self

Converts to this type from the input type.

impl From<f64> for Value

Panics if the value is NaN.

fn from(n: f64) -> Self

Converts to this type from the input type.

impl From<i32> for Value

fn from(n: i32) -> Self

Converts to this type from the input type.

impl From<i64> for Value

fn from(n: i64) -> Self

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.
