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§

Source§

impl Value

Source

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

Source

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

Source

pub fn to_out(&self) -> OutValue

The wire form placed in a proposal’s parameters.

Source

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.

Source

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

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

Source

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.
