name: Option<Option<String>>

The name of the observation

start_time: String

The start time of the observation

end_time: Option<Option<String>>

The end time of the observation.

completion_start_time: Option<Option<String>>

The completion start time of the observation

model: Option<Option<String>>

The model used for the observation

model_parameters: Option<Option<HashMap<String, MapValue>>>

The parameters of the model used for the observation

input: Option<Option<Value>>

The input data of the observation

version: Option<Option<String>>

The version of the observation

metadata: Option<Option<Value>>

Implementations

impl Observation

pub fn builder() -> ObservationBuilder

Create an instance of Observation using the builder syntax

impl Observation

pub fn new( id: String, type: String, start_time: String, level: ObservationLevel, ) -> Observation

Trait Implementations

impl Clone for Observation

fn clone(&self) -> Observation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Observation

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

Formats the value using the given formatter.

impl Default for Observation

fn default() -> Observation

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Observation

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Observation

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

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
