Struct Metadata 

#[non_exhaustive]
pub struct Metadata {
    pub generate_time: Option<Timestamp>,
    /* private fields */
}

Available on crate features feature-online-store-service or featurestore-online-serving-service only.

Metadata of feature value.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

generate_time: Option<Timestamp>

Feature generation timestamp. Typically, it is provided by user at feature ingestion time. If not, feature store will use the system timestamp when the data is ingested into feature store.

Legacy Feature Store: For streaming ingestion, the time, aligned by days, must be no older than five years (1825 days) and no later than one year (366 days) in the future.

Implementations

impl Metadata

pub fn new() -> Self

pub fn set_generate_time<T>(self, v: T) -> Self

where T: Into<Timestamp>,

Sets the value of generate_time.

Example

use wkt::Timestamp;
let x = Metadata::new().set_generate_time(Timestamp::default()/* use setters */);

pub fn set_or_clear_generate_time<T>(self, v: Option<T>) -> Self

where T: Into<Timestamp>,

Sets or clears the value of generate_time.

Example

use wkt::Timestamp;
let x = Metadata::new().set_or_clear_generate_time(Some(Timestamp::default()/* use setters */));
let x = Metadata::new().set_or_clear_generate_time(None::<Timestamp>);

Trait Implementations

impl Clone for Metadata

fn clone(&self) -> Metadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Metadata

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

Formats the value using the given formatter.

impl Default for Metadata

fn default() -> Metadata

Returns the “default value” for a type.

impl Message for Metadata

fn typename() -> &'static str

The typename of this message.

impl PartialEq for Metadata

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