Variants

Unspecified = 0

Code not specified.

IndexConfigNotAvailable = 1

Indicates the search index configuration has not been created.

PendingIndexCreation = 2

Indicates the search index creation has not been completed.

BaseTableTruncated = 3

Indicates the base table has been truncated (rows have been removed from table with TRUNCATE TABLE statement) since the last time the search index was refreshed.

IndexConfigModified = 4

Indicates the search index configuration has been changed since the last time the search index was refreshed.

TimeTravelQuery = 5

Indicates the search query accesses data at a timestamp before the last time the search index was refreshed.

NoPruningPower = 6

Indicates the usage of search index will not contribute to any pruning improvement for the search function, e.g. when the search predicate is in a disjunction with other non-search predicates.

UnindexedSearchFields = 7

Indicates the search index does not cover all fields in the search function.

UnsupportedSearchPattern = 8

Indicates the search index does not support the given search query pattern.

OptimizedWithMaterializedView = 9

Indicates the query has been optimized by using a materialized view.

SecuredByDataMasking = 11

Indicates the query has been secured by data masking, and thus search indexes are not applicable.

MismatchedTextAnalyzer = 12

Indicates that the search index and the search function call do not have the same text analyzer.

BaseTableTooSmall = 13

Indicates the base table is too small (below a certain threshold). The index does not provide noticeable search performance gains when the base table is too small.

BaseTableTooLarge = 14

Indicates that the total size of indexed base tables in your organization exceeds your region’s limit and the index is not used in the query. To index larger base tables, you can use> your own reservation for index-management jobs.

EstimatedPerformanceGainTooLow = 15

Indicates that the estimated performance gain from using the search index is too low for the given search query.

NotSupportedInStandardEdition = 17

Indicates that search indexes can not be used for search query with STANDARD edition.

IndexSuppressedByFunctionOption = 18

Indicates that an option in the search function that cannot make use of the index has been selected.

QueryCacheHit = 19

Indicates that the query was cached, and thus the search index was not used.

InternalError = 10

Indicates an internal error that causes the search index to be unused.

OtherReason = 16

Indicates that the reason search indexes cannot be used in the query is not covered by any of the other IndexUnusedReason options.

Implementations

impl Code

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of Code.

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

👎Deprecated: Use the TryFrom<i32> implementation instead

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

impl Code

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<Self>

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

Trait Implementations

impl Clone for Code

fn clone(&self) -> Code

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Code

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

Formats the value using the given formatter.

impl Default for Code

fn default() -> Code

Returns the “default value” for a type.

impl From<Code> for i32

fn from(value: Code) -> i32

Converts to this type from the input type.

impl Hash for Code

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 Ord for Code

fn cmp(&self, other: &Code) -> 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 Code

fn eq(&self, other: &Code) -> 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 Code

fn partial_cmp(&self, other: &Code) -> 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 Code

type Error = UnknownEnumValue

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<Code, UnknownEnumValue>

Performs the conversion.

impl Copy for Code

impl Eq for Code

impl StructuralPartialEq for Code
