Modules§

cow 🔒
data_types
Convenient macros to generate match arms for DataType.

Date, time, and timestamp types.

interval 🔒
jsonb 🔒
macros 🔒
map_type 🔒
native_type 🔒
num256 🔒
ops 🔒
ordered 🔒
ScalarImpl and Datum wrappers that implement PartialOrd and Ord with default order type.

postgres_type 🔒
private 🔒
scalar_impl 🔒
sentinel 🔒
serial 🔒
struct_type 🔒
successor 🔒
test_utils
A separate mod so that use types::* or use interval::* does not use IntervalTestExt by accident.
timestamptz 🔒

to_sql 🔒
to_text 🔒
with_data_type 🔒

Macros§

impl_convert 🔒
impl_convert implements several conversions for Scalar.
impl_self_as_scalar_ref 🔒
scalar_impl_enum 🔒
Define ScalarImpl and ScalarRefImpl with macro.

Structs§

Date
DefaultOrdered
Wrapper that delegates PartialOrd and Ord to the DefaultPartialOrd and DefaultOrd implementations of inner type.
Int256
A 256-bit signed integer.
Int256Ref
A reference to an Int256 value.
Interval
Every interval can be represented by a Interval.
IntervalDisplay
Wrapper so that Debug for IntervalDisplay would use the concise format of Display for Interval.
JsonbRef
JsonbVal
MapType
Refer to super::super::array::MapArray for the invariants of a map value.
Serial
StructType
A cheaply cloneable struct type.
Time
Timestamp
Timestamptz
Timestamp with timezone.

Enums§

DataType
The set of datatypes that are supported in RisingWave.
DataTypeName
Auto-generated discriminant enum variants
DateTimeField
DatumCow
🐮 A borrowed DatumRef or an owned Datum.
Decimal
DecimalPowError
ScalarImpl
ScalarImpl embeds all possible scalars in the evaluation framework.
ScalarRefImpl
ScalarRefImpl embeds all possible scalar references in the evaluation framework.
Sentinelled
Sentinelled<T> wraps type T to provide smallest (smaller than any normal T value) and largest (larger than ant normal T value) sentinel value for T.

Traits§

CheckedAdd
A more general version of num_traits::CheckedAdd that allows Rhs and Output to be different.
DefaultOrd
Variant of Ord that compares with default order.
DefaultPartialOrd
Fields
A struct can implements Fields when if can be represented as a relational Row.
FloatExt
Similar to num_traits::Float, but without requiring NumCast and ToPrimitive.
IntoOrdered
IsNegative
A simplified version of num_traits::Signed. Unlike Signed::is_negative or f64::is_sign_negative, this returns false for -0.0 to keep consistency among integers, decimals and floats.
NativeType
Scalar
Scalar is a trait over all possible owned types in the evaluation framework.
ScalarPartialOrd
ScalarPartialOrd allows comparison between Scalar and ScalarRef.
ScalarRef
ScalarRef is a trait over all possible references in the evaluation framework.
SelfAsScalarRef
To make sure there is as_scalar_ref for all scalar ref types. See https://github.com/risingwavelabs/risingwave/pull/9977/files#r1208972881
Successor
A successor is a term that comes right after a particular value. Suppose n is a number (where n belongs to any whole number), then the successor of n is ‘n+1’. The other terminologies used for a successor are just after, immediately after, and next value.
ToDatumRef
ToOwnedDatum
This trait is to implement to_owned_datum for Option<ScalarImpl>
ToText
Converts ScalarRef to pgwire “TEXT” format.
WithDataType
A trait for all physical types that can be associated with a DataType.

Functions§

default_partial_cmp_scalar_ref_impl
hash_datum
Feeds the raw scalar reference of datum to the given state, which should behave the same as crate::array::Array::hash_at, where NULL value will be carefully handled.
literal_type_match
Returns whether the literal matches the data_type.
write_date_time_tz

Type Aliases§

Datum
DatumRef
F32
A 32-bit floating point type with total order.
F64
A 64-bit floating point type with total order.
