/// A dynamically typed, nullable single value.
///
/// While an arrow  [`Array`]) stores one or more values of the same type, in a
/// single column, a `ScalarValue` stores a single value of a single type, the
/// equivalent of 1 row and one column.
///
/// ```text
///  ┌────────┐
///  │ value1 │
///  │ value2 │                  ┌────────┐
///  │ value3 │                  │ value2 │

///    Array                     ScalarValue
///
/// stores multiple,             stores a single,
/// possibly null, values of     possible null, value
/// the same type
/// ```
///
/// # Performance
///
/// In general, performance will be better using arrow [`Array`]s rather than
/// [`ScalarValue`], as it is far more efficient to process multiple values at
/// once (vectorized processing).
///
/// # Example
/// ```
/// # use datafusion_common::ScalarValue;
/// // Create single scalar value for an Int32 value
/// let s1 = ScalarValue::Int32(Some(10));
///
/// // You can also create values using the From impl:
/// let s2 = ScalarValue::from(10i32);
/// assert_eq!(s1, s2);
/// ```
///
/// # Null Handling
///
/// `ScalarValue` represents null values in the same way as Arrow. Nulls are
/// "typed" in the sense that a null value in an [`Int32Array`] is different
/// from a null value in a [`Float64Array`], and is different from the values in
/// a [`NullArray`].
///
/// ```
/// # fn main() -> datafusion_common::Result<()> {
/// # use std::collections::hash_set::Difference;
/// # use datafusion_common::ScalarValue;
/// # use arrow::datatypes::DataType;
/// // You can create a 'null' Int32 value directly:
/// let s1 = ScalarValue::Int32(None);
///
/// // You can also create a null value for a given datatype:
/// let s2 = ScalarValue::try_from(&DataType::Int32)?;
/// assert_eq!(s1, s2);
///
/// // Note that this is DIFFERENT than a `ScalarValue::Null`
/// let s3 = ScalarValue::Null;
/// assert_ne!(s1, s3);
/// # Ok(())
/// # }
/// ```
///
/// # Nested Types
///
/// `List` / `LargeList` / `FixedSizeList` / `Struct` / `Map` are represented as a
/// single element array of the corresponding type.
///
/// ## Example: Creating [`ScalarValue::Struct`] using [`ScalarStructBuilder`]
/// ```
/// # use std::sync::Arc;
/// # use arrow::datatypes::{DataType, Field};
/// # use datafusion_common::{ScalarValue, scalar::ScalarStructBuilder};
/// // Build a struct like: {a: 1, b: "foo"}
/// let field_a = Field::new("a", DataType::Int32, false);
/// let field_b = Field::new("b", DataType::Utf8, false);
///
/// let s1 = ScalarStructBuilder::new()
///    .with_scalar(field_a, ScalarValue::from(1i32))
///    .with_scalar(field_b, ScalarValue::from("foo"))
///    .build();
/// ```
///
/// ## Example: Creating a null [`ScalarValue::Struct`] using [`ScalarStructBuilder`]
/// ```
/// # use std::sync::Arc;
/// # use arrow::datatypes::{DataType, Field};
/// # use datafusion_common::{ScalarValue, scalar::ScalarStructBuilder};
/// // Build a struct representing a NULL value
/// let fields = vec![
///     Field::new("a", DataType::Int32, false),
///     Field::new("b", DataType::Utf8, false),
/// ];
///
/// let s1 = ScalarStructBuilder::new_null(fields);
/// ```
///

/// # use datafusion_common::ScalarValue;
/// // Build a struct like: {a: 1, b: "foo"}
/// // Field description
/// let fields = Fields::from(vec![
///   Field::new("a", DataType::Int32, false),
