Struct opentelemetry_sdk::logs::LogRecord

#[non_exhaustive]
pub struct LogRecord {
    pub event_name: Option<Cow<'static, str>>,

    pub timestamp: Option<SystemTime>,
    pub observed_timestamp: Option<SystemTime>,

LogRecord represents all data carried by a log record, and is provided to LogExporters as input.

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.

event_name: Option<Cow<'static, str>>

Event name. Optional as not all the logging API support it.

target: Option<Cow<'static, str>>

Target of the log record

timestamp: Option<SystemTime>

Record timestamp

observed_timestamp: Option<SystemTime>

Timestamp for when the record was observed by OpenTelemetry

trace_context: Option<TraceContext>

Trace context for logs associated with spans

severity_text: Option<Cow<'static, str>>

The original severity string from the source

severity_number: Option<Severity>

The corresponding severity value, normalized

body: Option<AnyValue>

Record body

attributes: Option<Vec<(Key, AnyValue)>>

Additional attributes associated with this record

Trait Implementations

impl Clone for LogRecord

fn clone(&self) -> LogRecord

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LogRecord

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

Formats the value using the given formatter.

impl Default for LogRecord

fn default() -> LogRecord

Returns the “default value” for a type.

impl LogRecord for LogRecord

fn set_event_name<T>(&mut self, name: T)

where T: Into<Cow<'static, str>>,

Sets the event_name of a record

fn set_target<T>(&mut self, _target: T)

where T: Into<Cow<'static, str>>,

Sets the target of a record. Currently, both opentelemetry-appender-tracing and opentelemetry-appender-log create a single logger with a scope that doesn’t accurately reflect the component emitting the logs. Exporters MAY use this field to override the instrumentation_scope.name.

fn set_timestamp(&mut self, timestamp: SystemTime)

Sets the time when the event occurred measured by the origin clock, i.e. the time at the source.

fn set_observed_timestamp(&mut self, timestamp: SystemTime)

Sets the observed event timestamp.

fn set_severity_text(&mut self, severity_text: Cow<'static, str>)

Sets severity as text.

fn set_severity_number(&mut self, severity_number: Severity)

Sets severity as a numeric value.

fn set_body(&mut self, body: AnyValue)

Sets the message body of the log.

fn add_attributes<I, K, V>(&mut self, attributes: I)

where I: IntoIterator<Item = (K, V)>, K: Into<Key>, V: Into<AnyValue>,

Adds multiple attributes.

fn add_attribute<K, V>(&mut self, key: K, value: V)

where K: Into<Key>, V: Into<AnyValue>,

Adds a single attribute.
