Enum spark_connect_rs::dataframe::ExplainMode

}

Plan explanation mode.

Variants

Unspecified = 0

Simple = 1

Generates only physical plan.

Extended = 2

Generates parsed logical plan, analyzed logical plan, optimized logical plan and physical plan. Parsed Logical plan is a unresolved plan that extracted from the query. Analyzed logical plans transforms which translates unresolvedAttribute and unresolvedRelation into fully typed objects. The optimized logical plan transforms through a set of optimization rules, resulting in the physical plan.

Codegen = 3

Generates code for the statement, if any and a physical plan.

Cost = 4

If plan node statistics are available, generates a logical plan and also the statistics.

Formatted = 5

Generates a physical plan outline and also node details.

Implementations

impl ExplainMode

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of ExplainMode.

pub fn from_i32(value: i32) -> Option<ExplainMode>

👎Deprecated: Use the TryFrom<i32> implementation instead

Converts an i32 to a ExplainMode, or None if value is not a valid variant.

impl ExplainMode

pub fn as_str_name(&self) -> &'static str

String value of the enum field names used in the ProtoBuf definition.

The values are not transformed in any way and thus are considered stable (if the ProtoBuf definition does not change) and safe for programmatic use.

pub fn from_str_name(value: &str) -> Option<ExplainMode>

Creates an enum from field names used in the ProtoBuf definition.

Trait Implementations

impl Clone for ExplainMode

fn clone(&self) -> ExplainMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExplainMode

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

Formats the value using the given formatter.

impl Default for ExplainMode

fn default() -> ExplainMode

Returns the “default value” for a type.

impl Hash for ExplainMode

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

where __H: Hasher,

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 Ord for ExplainMode

fn cmp(&self, other: &ExplainMode) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for ExplainMode

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for ExplainMode

fn partial_cmp(&self, other: &ExplainMode) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl TryFrom<i32> for ExplainMode

type Error = DecodeError

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<ExplainMode, DecodeError>

Performs the conversion.
