case class StructType(fields: Array[StructField]) extends DataType with Seq[StructField] with Product with Serializable

A StructType object can be constructed by

StructType(fields: Seq[StructField])

For a StructType object, one or multiple StructFields can be extracted by names. If multiple StructFields are extracted, a StructType object will be returned. If a provided name does not have a matching field, it will be ignored. For the case of extracting a single StructField, a null will be returned.

Scala Example:

import org.apache.spark.sql._
import org.apache.spark.sql.types._

val struct =
  StructType(
    StructField("a", IntegerType, true) ::
    StructField("b", LongType, false) ::
    StructField("c", BooleanType, false) :: Nil)

// Extract a single StructField.
val singleField = struct("b")
// singleField: StructField = StructField(b,LongType,false)

// If this struct does not have a field called "d", it throws an exception.
struct("d")
// java.lang.IllegalArgumentException: Field "d" does not exist.
//   ...

// Extract multiple StructFields. Field names are provided in a set.
// A StructType object will be returned.
val twoFields = struct(Set("b", "c"))
// twoFields: StructType =
//   StructType(StructField(b,LongType,false), StructField(c,BooleanType,false))

// Any names without matching fields will throw an exception.
// For the case shown below, an exception is thrown due to "d".
struct(Set("b", "c", "d"))
// java.lang.IllegalArgumentException: Field "d" does not exist.
//    ...

A org.apache.spark.sql.Row object is used as a value of the StructType.

Scala Example:

import org.apache.spark.sql._
import org.apache.spark.sql.types._

val innerStruct =
  StructType(
    StructField("f1", IntegerType, true) ::
    StructField("f2", LongType, false) ::
    StructField("f3", BooleanType, false) :: Nil)

val struct = StructType(
  StructField("a", innerStruct, true) :: Nil)

// Create a Row with the schema defined by struct
val row = Row(Row(1, 2, true))
