Struct Event 

#[non_exhaustive]
pub struct Event {
    pub dimensions: Vec<EventDimension>,
    pub group_id: i64,
    pub event_time: Option<Timestamp>,
    /* private fields */
}

Represents an entry in a data source.

Each Event has:

• A timestamp at which the event occurs.
• One or multiple dimensions.
• Optionally, a group ID that allows clients to group logically related events (for example, all events representing payments transactions done by a user in a day have the same group ID). If a group ID is not provided, an internal one will be generated based on the content and eventTime.

NOTE:

• Internally, we discretize time in equal-sized chunks and we assume an event has a 0 TimeseriesPoint.value in a chunk that does not contain any occurrences of an event in the input.
• The number of Events with the same group ID should be limited.
• Group ID cannot be queried.
• Group ID does not correspond to a user ID or the like. If a user ID is of interest to be queried, use a user ID dimension instead.

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.

dimensions: Vec<EventDimension>

Event dimensions.

group_id: i64

Event group ID.

NOTE: JSON encoding should use a string to hold a 64-bit integer value, because a native JSON number holds only 53 binary bits for an integer.

event_time: Option<Timestamp>

Event timestamp.

Implementations

impl Event

pub fn new() -> Self

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

where T: IntoIterator<Item = V>, V: Into<EventDimension>,

Sets the value of dimensions.

pub fn set_group_id<T: Into<i64>>(self, v: T) -> Self

Sets the value of group_id.

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

where T: Into<Timestamp>,

Sets the value of event_time.

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

where T: Into<Timestamp>,

Sets or clears the value of event_time.

Trait Implementations

impl Clone for Event

fn clone(&self) -> Event

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Event

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

Formats the value using the given formatter.

impl Default for Event

fn default() -> Event

Returns the “default value” for a type.

impl Message for Event

fn typename() -> &'static str

The typename of this message.

impl PartialEq for Event

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