Struct vector_core::event::LogEvent

pub struct LogEvent { /* private fields */ }

Implementations

impl LogEvent

pub fn from_str_legacy(msg: impl Into<String>) -> Self

This used to be the implementation for LogEvent::from(&'str), but this is now only valid for LogNamespace::Legacy

pub fn from_bytes_legacy(msg: &Bytes) -> Self

This used to be the implementation for LogEvent::from(Bytes), but this is now only valid for LogNamespace::Legacy

pub fn value(&self) -> &Value

pub fn value_mut(&mut self) -> &mut Value

pub fn metadata(&self) -> &EventMetadata

pub fn metadata_mut(&mut self) -> &mut EventMetadata

pub fn namespace(&self) -> LogNamespace

This detects the log namespace used at runtime by checking for the existence of the read-only “vector” metadata, which only exists (and is required to exist) with the Vector log namespace.

impl LogEvent

pub fn new_with_metadata(metadata: EventMetadata) -> Self

pub fn from_parts(value: Value, metadata: EventMetadata) -> Self

Create a LogEvent from a Value and EventMetadata

pub fn from_map(map: ObjectMap, metadata: EventMetadata) -> Self

Create a LogEvent from an ObjectMap and EventMetadata

pub fn into_parts(self) -> (Value, EventMetadata)

Convert a LogEvent into a tuple of its components

pub fn with_batch_notifier(self, batch: &BatchNotifier) -> Self

pub fn with_batch_notifier_option(self, batch: &Option<BatchNotifier>) -> Self

pub fn add_finalizer(&mut self, finalizer: EventFinalizer)

pub fn parse_path_and_get_value( &self, path: impl AsRef<str>, ) -> Result<Option<&Value>, PathParseError>

Parse the specified path and if there are no parsing errors, attempt to get a reference to a value.

Errors

Will return an error if path parsing failed.

pub fn get<'a>(&self, key: impl TargetPath<'a>) -> Option<&Value>

pub fn get_by_meaning(&self, meaning: impl AsRef<str>) -> Option<&Value>

Retrieves the value of a field based on it’s meaning. This will first check if the value has previously been dropped. It is worth being aware that if the field has been dropped and then somehow re-added, we still fetch the dropped value here.

pub fn get_mut_by_meaning( &mut self, meaning: impl AsRef<str>, ) -> Option<&mut Value>

Retrieves the mutable value of a field based on it’s meaning. Note that this does not check the dropped fields, unlike get_by_meaning, since the purpose of the mutable reference is to be able to modify the value and modifying the dropped fields has no effect on the resulting event.

pub fn find_key_by_meaning( &self, meaning: impl AsRef<str>, ) -> Option<&OwnedTargetPath>

Retrieves the target path of a field based on the specified meaning.

pub fn get_mut<'a>(&mut self, path: impl TargetPath<'a>) -> Option<&mut Value>

pub fn contains<'a>(&self, path: impl TargetPath<'a>) -> bool

pub fn parse_path_and_insert( &mut self, path: impl AsRef<str>, value: impl Into<Value>, ) -> Result<Option<Value>, PathParseError>

Parse the specified path and if there are no parsing errors, attempt to insert the specified value.

Errors

Will return an error if path parsing failed.

pub fn insert<'a>( &mut self, path: impl TargetPath<'a>, value: impl Into<Value>, ) -> Option<Value>

pub fn maybe_insert<'a>( &mut self, path: Option<impl TargetPath<'a>>, value: impl Into<Value>, )

pub fn try_insert<'a>( &mut self, path: impl TargetPath<'a>, value: impl Into<Value>, )

pub fn rename_key<'a>( &mut self, from: impl TargetPath<'a>, to: impl TargetPath<'a>, )

Rename a key

If to_key already exists in the structure its value will be overwritten.

pub fn remove<'a>(&mut self, path: impl TargetPath<'a>) -> Option<Value>

pub fn remove_prune<'a>( &mut self, path: impl TargetPath<'a>, prune: bool, ) -> Option<Value>

pub fn keys(&self) -> Option<impl Iterator<Item = KeyString> + '_>

pub fn all_event_fields( &self, ) -> Option<impl Iterator<Item = (KeyString, &Value)> + Serialize>

If the event root value is a map, build and return an iterator to event field and value pairs. TODO: Ideally this should return target paths to be consistent with other LogEvent methods.

pub fn all_event_fields_skip_array_elements( &self, ) -> Option<impl Iterator<Item = (KeyString, &Value)> + Serialize>

Similar to LogEvent::all_event_fields, but doesn’t traverse individual array elements.

pub fn all_metadata_fields( &self, ) -> Option<impl Iterator<Item = (KeyString, &Value)> + Serialize>

If the metadata root value is a map, build and return an iterator to metadata field and value pairs. TODO: Ideally this should return target paths to be consistent with other LogEvent methods.

pub fn convert_to_fields( &self, ) -> impl Iterator<Item = (KeyString, &Value)> + Serialize

Returns an iterator of all fields if the value is an Object. Otherwise, a single field is returned with a “message” key. Field names that are could be interpreted as alternate paths (i.e. containing periods, square brackets, etc) are quoted.

pub fn convert_to_fields_unquoted( &self, ) -> impl Iterator<Item = (KeyString, &Value)> + Serialize

Returns an iterator of all fields if the value is an Object. Otherwise, a single field is returned with a “message” key. Field names are not quoted.

pub fn is_empty_object(&self) -> bool

pub fn as_map(&self) -> Option<&ObjectMap>

pub fn as_map_mut(&mut self) -> Option<&mut ObjectMap>

pub fn merge(&mut self, incoming: LogEvent, fields: &[impl AsRef<str>])

Merge all fields specified at fields from incoming to current. Note that fields containing dots and other special characters will be treated as a single segment.

impl LogEvent

Log Namespace utility methods. These can only be used when an event has a valid schema definition set (which should be on every event in transforms and sinks).

pub fn message_path(&self) -> Option<&OwnedTargetPath>

pub fn host_path(&self) -> Option<&OwnedTargetPath>

Fetches the host path of the event. This is either from the “host” semantic meaning (Vector namespace) or from the host key set on the “Global Log Schema” (Legacy namespace).

pub fn source_type_path(&self) -> Option<&OwnedTargetPath>

pub fn get_message(&self) -> Option<&Value>

Fetches the message of the event. This is either from the “message” semantic meaning (Vector namespace) or from the message key set on the “Global Log Schema” (Legacy namespace).

pub fn get_timestamp(&self) -> Option<&Value>

pub fn remove_timestamp(&mut self) -> Option<Value>

Removes the timestamp from the event. This is either from the “timestamp” semantic meaning (Vector namespace) or from the timestamp key set on the “Global Log Schema” (Legacy namespace).

pub fn get_host(&self) -> Option<&Value>

Fetches the host of the event. This is either from the “host” semantic meaning (Vector namespace) or from the host key set on the “Global Log Schema” (Legacy namespace).

pub fn get_source_type(&self) -> Option<&Value>

Fetches the source_type of the event. This is either from the source_type Vector metadata field (Vector namespace) or from the source_type key set on the “Global Log Schema” (Legacy namespace).
