Creates an array from a literal slice of values, suitable for rapid testing and development.

Example:

use arrow_array::create_array;

let array = create_array!(Int32, [1, 2, 3, 4, 5]);
let array = create_array!(Utf8, [Some("a"), Some("b"), None, Some("e")]);

Support for limited data types is available. The macro will return a compile error if an unsupported data type is used. Presently supported data types are:

• Boolean, Null
• Decimal128, Decimal256
• Float16, Float32, Float64
• Int8, Int16, Int32, Int64
• UInt8, UInt16, UInt32, UInt64
• IntervalDayTime, IntervalYearMonth
• Second, Millisecond, Microsecond, Nanosecond
• Second32, Millisecond32, Microsecond64, Nanosecond64
• DurationSecond, DurationMillisecond, DurationMicrosecond, DurationNanosecond
• TimestampSecond, TimestampMillisecond, TimestampMicrosecond, TimestampNanosecond
• Utf8, Utf8View, LargeUtf8, Binary, LargeBinary
