Enum Value 

pub enum Value {
    Int(i64),
    Float(f64),
    Bool(bool),
    Str(String),
    DateTime(i64),
    Uuid([u8; 16]),
    Bytes(Vec<u8>),
    Json(Box<[u8]>),
    Empty,
}

A single scalar value. Optional fields use Empty (set-based nullability).

Variants

Int(i64)

Float(f64)

Bool(bool)

Str(String)

DateTime(i64)

Uuid([u8; 16])

Bytes(Vec<u8>)

Json(Box<[u8]>)

Canonical PJ1 (binary JSON) bytes. Rendered as canonical JSON text on the wire; ordered by the PJ1 total order. See crate::pj1.

Empty

Implementations

impl Value

pub fn type_id(&self) -> TypeId

pub fn encoded_size(&self) -> usize

Number of bytes this value occupies when encoded in a row.

pub fn is_empty(&self) -> bool

pub fn to_wire_string(&self) -> String

Canonical wire/text rendering of a value, shared by the server protocol, the CLI, and the embedded bindings so a result is identical however it is read. Empty (NULL) renders as the bareword null — the sentinel the typed-row decoders recognize; a UUID renders as the canonical hyphenated form; bytes render as a <N bytes> placeholder (the binary wire path does not stringify raw bytes).

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 Eq for Value

impl Hash for Value

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Value

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Value

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Value

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
