Enum EvalMode 

pub enum EvalMode {
    Legacy,
    Ansi,
    Try,
}

Spark supports three evaluation modes when evaluating expressions, which affect the behavior when processing input values that are invalid or would result in an error, such as divide by zero errors, and also affects behavior when converting between types.

Variants

Legacy

Legacy is the default behavior in Spark prior to Spark 4.0. This mode silently ignores or replaces errors during SQL operations. Operations resulting in errors (like division by zero) will produce NULL values instead of failing. Legacy mode also enables implicit type conversions.

Ansi

Adheres to the ANSI SQL standard for error handling by throwing exceptions for operations that result in errors. Does not perform implicit type conversions.

Try

Same as Ansi mode, except that it converts errors to NULL values without failing the entire query.

Trait Implementations

impl Clone for EvalMode

fn clone(&self) -> EvalMode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EvalMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for EvalMode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for EvalMode

fn eq(&self, other: &EvalMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
