Enum Code 

#[non_exhaustive]
pub enum Code {
    Unspecified,
    NoReservation,
    InsufficientReservation,
    UnsupportedSqlText,
    InputTooLarge,
    OtherReason,
    TableExcluded,
    UnknownValue(UnknownValue),
}

Indicates the high-level reason for no/partial acceleration

Working with unknown values

This enum is defined as #[non_exhaustive] because Google Cloud may add additional enum variants at any time. Adding new variants is not considered a breaking change. Applications should write their code in anticipation of:

• New values appearing in future releases of the client library, and
• New values received dynamically, without application changes.

Please consult the Working with enums section in the user guide for some guidelines.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Unspecified

BiEngineReason not specified.

NoReservation

No reservation available for BI Engine acceleration.

InsufficientReservation

Not enough memory available for BI Engine acceleration.

UnsupportedSqlText

This particular SQL text is not supported for acceleration by BI Engine.

InputTooLarge

Input too large for acceleration by BI Engine.

OtherReason

Catch-all code for all other cases for partial or disabled acceleration.

TableExcluded

One or more tables were not eligible for BI Engine acceleration.

UnknownValue(UnknownValue)

If set, the enum was initialized with an unknown value.

Applications can examine the value using Code::value or Code::name.

Implementations

impl Code

pub fn value(&self) -> Option<i32>

Gets the enum value.

Returns None if the enum contains an unknown value deserialized from the string representation of enums.

pub fn name(&self) -> Option<&str>

Gets the enum value as a string.

Returns None if the enum contains an unknown value deserialized from the integer representation of enums.

Trait Implementations

impl Clone for Code

fn clone(&self) -> Code

Returns a duplicate 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() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Code

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Code

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

Formats the value using the given formatter.

impl From<&str> for Code

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<i32> for Code

fn from(value: i32) -> Self

Converts to this type from the input type.

impl PartialEq for Code

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for Code

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,
