    Bool(bool),
    Integer(i64),
    Decimal(Decimal),
    Text(String),
    Enum(String),
    Timestamp(Timestamp),
    Duration(DurationMs),

An exact value.

Variants

Bool(bool)

Integer(i64)

Decimal(Decimal)

Text(String)

Enum(String)

Timestamp(Timestamp)

Duration(DurationMs)

Maybe(Option<Box<Value>>)

List(Vec<Value>)

Record(BTreeMap<String, Value>)

Filtered(Filtered)

Shortlist(Shortlist)

Ranking(Ranking)

Null

A null nullable field (spec 032, 3.4.1).

Absent(Absence)

A value that failed its presence predicate, or a merged field that could not be filled (spec 032, 3.4.3 and 3.6.2). Reading it is missing_evidence; it is never a present value with empty fields.

Map(BTreeMap<String, Value>)

Joined(Vec<JoinEntry>)

Implementations

impl Value

pub fn from_literal(l: &Literal) -> Value

pub fn literal_ty(l: &Literal) -> Ty

pub fn to_out(&self) -> OutValue

The wire form placed in a proposal’s parameters.

pub fn to_json(&self) -> Json

The JSON used in projections and conflict comparison. Decimals are strings and there are no fractional numbers, so it has canonical bytes.

pub fn id_bounds(ty: &Ty) -> Option<(u64, u64)>

Maximum count and byte length of the ids an id-bearing type carries.

pub fn ids(&self) -> Option<Vec<String>>

The ids of an id-bearing value: a text list, a filter’s eligible ids, a shortlist’s ids.

Trait Implementations

impl Clone for Value

fn clone(&self) -> Self

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 PartialEq for Value

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

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for Value
