Implementations

impl Value

pub fn cast_to(&self, target_type: ValueType) -> Result<Value, CastError>

Cast this value to the specified target type

pub fn try_cast_to(&self, target_type: ValueType) -> Option<Value>

Try to cast this value to the specified target type, returning None if the cast fails

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 Collatable for Value

fn to_bytes(&self) -> Vec<u8>

fn successor_bytes(&self) -> Option<Vec<u8>>

Returns the immediate successor’s binary representation if one exists

fn predecessor_bytes(&self) -> Option<Vec<u8>>

Returns the immediate predecessor’s binary representation if one exists

fn is_in_range( &self, lower: RangeBound<&Self>, upper: RangeBound<&Self>, ) -> bool

impl Debug for Value

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

Formats the value using the given formatter.

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

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

Formats the value using the given formatter.

impl From<&Literal> for Value

fn from(literal: &Literal) -> Self

Converts to this type from the input type.

impl From<&Value> for Literal

fn from(value: &Value) -> Self

Converts to this type from the input type.

impl From<&str> for Value

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<EntityId> for Value

fn from(value: EntityId) -> Self

Converts to this type from the input type.

impl From<Literal> for Value

fn from(literal: Literal) -> Self

Converts to this type from the input type.

impl From<String> for Value

fn from(value: String) -> Self

Converts to this type from the input type.

impl From<Value> for Literal

fn from(value: Value) -> Self

Converts to this type from the input type.

impl From<Vec<u8>> for Value

fn from(value: Vec<u8>) -> Self

Converts to this type from the input type.
