Traits

• ArrowDictionaryKeyType
  A subtype of primitive type that represents legal dictionary keys. See https://arrow.apache.org/docs/format/Columnar.html
• ArrowPrimitiveType
  Trait bridging the dynamic-typed nature of Arrow (via DataType) with the static-typed nature of rust types (ArrowNativeType) for all types that implement ArrowNativeType.
• ArrowTemporalType
  A subtype of primitive type that represents temporal values.
• ArrowTimestampType
  A timestamp type allows us to create array builders that take a timestamp.
• ByteArrayType
  A trait over the variable-size byte array types
• ByteViewType
  A trait over the variable length bytes view array types
• DecimalType
  A trait over the decimal types, used by PrimitiveArray to provide a generic implementation across the various decimal types
• RunEndIndexType
  A subtype of primitive type that is used as run-ends index in RunArray. See https://arrow.apache.org/docs/format/Columnar.html

Functions
