Struct EventBuilder 

pub struct EventBuilder<S: State = Empty> { /* private fields */ }

Use builder syntax to set the inputs and finish with call().

Implementations

impl<S: State> EventBuilder<S>

pub fn call(self)

where S: IsComplete,

Finishes building and performs the requested action.

pub fn level(self, value: EventLevel) -> EventBuilder<SetLevel<S>>

where S::Level: IsUnset,

Optional (Some / Option setters). Default: EventLevel::Info.

pub fn maybe_level(self, value: Option<EventLevel>) -> EventBuilder<SetLevel<S>>

where S::Level: IsUnset,

Optional (Some / Option setters). Default: EventLevel::Info.

pub fn message(self, value: impl Into<String>) -> EventBuilder<SetMessage<S>>

where S::Message: IsUnset,

Optional (Some / Option setters). Default: "".

pub fn maybe_message( self, value: Option<impl Into<String>>, ) -> EventBuilder<SetMessage<S>>

where S::Message: IsUnset,

Optional (Some / Option setters). Default: "".

pub fn timestamp(self, value: SystemTime) -> EventBuilder<SetTimestamp<S>>

where S::Timestamp: IsUnset,

Optional (Some / Option setters).

pub fn maybe_timestamp( self, value: Option<SystemTime>, ) -> EventBuilder<SetTimestamp<S>>

where S::Timestamp: IsUnset,

Optional (Some / Option setters).

impl<S: State> EventBuilder<S>

Custom methods for the event builder to support individual attribute calls

pub fn attribute(self, key: impl Into<String>, value: impl Into<Value>) -> Self

Add a single attribute to the event.

This method accepts any value that can be converted to an OpenTelemetry Value, including strings, numbers, booleans, and other supported types.

Examples

use lambda_otel_lite::events::{event, EventLevel};

event()
    .level(EventLevel::Info)
    .message("User action")
    .attribute("user_id", "123")        // String
    .attribute("count", 42)             // Integer
    .attribute("score", 98.5)           // Float
    .attribute("is_admin", true)        // Boolean
    .call();

pub fn add_attributes(self, attrs: Vec<KeyValue>) -> Self

Add multiple attributes at once from a vector.

This is useful when you have a collection of attributes to add.

Examples

use lambda_otel_lite::events::{event, EventLevel};
use opentelemetry::KeyValue;

event()
    .level(EventLevel::Info)
    .message("Batch operation")
    .add_attributes(vec![
        KeyValue::new("batch_id", "batch_123"),
        KeyValue::new("item_count", 100),
    ])
    .call();
