Module scalar 

Scalar values and types for the Vortex system.

This crate provides scalar types and values that can be used to represent individual data elements in the Vortex array system. Scalars are composed of a logical data type (DType) and an optional (encoding nullablity) value (ScalarValue).

Note that the implementations of Scalar are split into several different modules.

Modules

arbitrary

Arbitrary scalar value generation.

Structs

BinaryScalar

A scalar value representing binary data.

BoolScalar

A scalar value representing a boolean.

DecimalScalar

A scalar value representing a decimal number with fixed precision and scale.

ExtScalar

A scalar value representing an extension type.

ListScalar

A scalar value representing a list or fixed-size list (array) of elements.

PrimitiveScalar

A scalar value representing a primitive type.

Scalar

A typed scalar value.

StructScalar

A scalar value representing a struct with named fields.

Utf8Scalar

A scalar value representing a UTF-8 encoded string.

Enums

DecimalValue

A decimal value that can be stored in various integer widths.

NumericOperator

Binary element-wise operations on two arrays or two scalars.

PValue

A primitive value that can represent any primitive type supported by Vortex.

ScalarValue

The value stored in a Scalar.

Traits

ScalarTruncation

A trait for truncating Scalars to a given length in bytes.

StringLike

Types that can hold a valid UTF-8 string.

Functions

lower_bound

Truncate the value to be less than max_length in bytes and be lexicographically smaller than the value itself

upper_bound

Truncate the value to be less than max_length in bytes and be lexicographically greater than the value itself
