Variants

Null

SQL NULL.

Bool(bool)

Int2(i16)

Int4(i32)

Int8(i64)

Float4(f32)

Float8(f64)

Numeric(Numeric)

Oid(u32)

oid, xid, cid and the OID alias types.

Char(u8)

The type "char". The byte 0 is the empty string.

Text(String)

The string types, unknown, cstring, json and the other types that the engine keeps as their text form.

Bytea(Vec<u8>)

Uuid([u8; 16])

Date(i32)

date, the days since 1 January 2000.

Time(i64)

time, the microseconds since midnight.

TimeTz(i64, i32)

timetz, the microseconds since midnight and the zone offset in seconds west of UTC.

Timestamp(i64)

timestamp, the microseconds since 1 January 2000.

TimestampTz(i64)

timestamptz, the microseconds since 1 January 2000 UTC.

Interval(Interval)

Inet(Inet)

inet and cidr.

Array(Box<Array<Value>>)

An array, int2vector or oidvector. A null element is None, and no element is Some(Value::Null).

Record(Box<Record>)

A row of a composite type or of record.

Range(Box<Range>)

A value of a range type.

Multirange(Vec<Range>)

A value of a multirange type: the ranges in order, with no empty range and no two ranges that overlap or touch.

TsVector(Vec<Lexeme>)

A value of tsvector: the lexemes in order.

TsQuery(Vec<QueryItem>)

A value of tsquery: the operands and operators in prefix order, or no items for a query with no lexemes.

JsonPath(Box<JsonPath>)

A value of jsonpath.
