Module datafusion_common::scalar

This module provides ScalarValue, an enum that can be used for storage of single elements

Enums

• ScalarValue
  Represents a dynamically typed, nullable single value. This is the single-valued counter-part to arrow’s Array.

Traits

• ScalarType
  Trait used to map a NativeType to a ScalarValue

Functions

• dt_to_micro
  This function computes the duration (in microseconds) of the given daytime-interval.
• dt_to_milli
  This function computes the duration (in milliseconds) of the given daytime-interval.
• dt_to_nano
  This function computes the duration (in nanoseconds) of the given daytime-interval.
• dt_to_sec
  This function computes the duration (in seconds) of the given daytime-interval.
