Enum ObservationNoise 

#[non_exhaustive]
pub enum ObservationNoise {
    Unspecified,
    Low,
    High,
    UnknownValue(UnknownValue),
}

Available on crate features job-service or vizier-service only.

Describes the noise level of the repeated observations.

“Noisy” means that the repeated observations with the same Trial parameters may lead to different metric evaluations.

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

The default noise level chosen by Vertex AI.

Low

Vertex AI assumes that the objective function is (nearly) perfectly reproducible, and will never repeat the same Trial parameters.

High

Vertex AI will estimate the amount of noise in metric evaluations, it may repeat the same Trial parameters more than once.

UnknownValue(UnknownValue)

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

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

Implementations

impl ObservationNoise

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 ObservationNoise

fn clone(&self) -> ObservationNoise

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ObservationNoise

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

Formats the value using the given formatter.

impl Default for ObservationNoise

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ObservationNoise

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ObservationNoise

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

Formats the value using the given formatter.

impl From<&str> for ObservationNoise

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<i32> for ObservationNoise

fn from(value: i32) -> Self

Converts to this type from the input type.

impl PartialEq for ObservationNoise

fn eq(&self, other: &ObservationNoise) -> 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.

impl Serialize for ObservationNoise

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

where S: Serializer,

Serialize this value into the given Serde serializer.
