Variants

Null(LogicalType)

Bool(bool)

Int64(i64)

Int32(i32)

Int16(i16)

Int8(i8)

UInt64(u64)

UInt32(u32)

UInt16(u16)

UInt8(u8)

Int128(i128)

Double(f64)

Float(f32)

Date(Date)

Stored internally as the number of days since 1970-01-01 as a 32-bit signed integer, which allows for a wider range of dates to be stored than can be represented by time::Date

https://kuzudb.com/docusaurus/cypher/data-types/date.html

Interval(Duration)

May be signed or unsigned.

Nanosecond precision of time::Duration (if available) will not be preserved when passed to queries, and results will always have at most microsecond precision.

https://kuzudb.com/docusaurus/cypher/data-types/interval.html

Timestamp(OffsetDateTime)

Stored internally as the number of microseconds since 1970-01-01 Nanosecond precision of SystemTime (if available) will not be preserved when used.

https://kuzudb.com/docusaurus/cypher/data-types/timestamp.html

TimestampTz(OffsetDateTime)

TimestampNs(OffsetDateTime)

TimestampMs(OffsetDateTime)

TimestampSec(OffsetDateTime)

InternalID(InternalID)

String(String)

https://kuzudb.com/docusaurus/cypher/data-types/string.html

Blob(Vec<u8>)

List(LogicalType, Vec<Value>)

These must contain elements which are all the given type. https://kuzudb.com/docusaurus/cypher/data-types/list.html

Array(LogicalType, Vec<Value>)

These must contain elements which are all the same type. https://kuzudb.com/docusaurus/cypher/data-types/list.html

Struct(Vec<(String, Value)>)

https://kuzudb.com/docusaurus/cypher/data-types/struct.html

Node(NodeVal)

Rel(RelVal)

RecursiveRel

Fields

nodes: Vec<NodeVal>

Interior nodes in the Sequence of Rels

Does not include the starting or ending Node.

rels: Vec<RelVal>

Sequence of Rels which make up the RecursiveRel

Map((LogicalType, LogicalType), Vec<(Value, Value)>)

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a copy 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 LogicalType

fn from(value: &Value) -> Self

Converts to this type from the input type.

impl From<&str> for Value

fn from(item: &str) -> Self

Converts to this type from the input type.

impl From<String> for Value

fn from(item: String) -> Self

Converts to this type from the input type.

impl From<f32> for Value

fn from(item: f32) -> Self

Converts to this type from the input type.

impl From<f64> for Value

fn from(item: f64) -> Self

Converts to this type from the input type.

impl From<i128> for Value

fn from(item: i128) -> Self

Converts to this type from the input type.

impl From<i16> for Value

fn from(item: i16) -> Self

Converts to this type from the input type.

impl From<i32> for Value

fn from(item: i32) -> Self

Converts to this type from the input type.

impl From<i64> for Value

fn from(item: i64) -> Self

Converts to this type from the input type.

impl From<i8> for Value

fn from(item: i8) -> Self

Converts to this type from the input type.

impl From<u16> for Value

fn from(item: u16) -> Self

Converts to this type from the input type.

impl From<u32> for Value

fn from(item: u32) -> Self

Converts to this type from the input type.

impl From<u64> for Value

fn from(item: u64) -> Self

Converts to this type from the input type.

impl From<u8> for Value

fn from(item: u8) -> Self

Converts to this type from the input type.

impl PartialEq for Value

fn eq(&self, other: &Value) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryInto<UniquePtr<Value>> for Value

type Error = Error

The type returned in the event of a conversion error.

fn try_into(self) -> Result<UniquePtr<Value>, Self::Error>

Performs the conversion.

impl StructuralPartialEq for Value
