Struct tracing_fluentd::Builder

pub struct Builder<F = NestedFmt, A = fn() -> Result<TcpStream>> { /* fields omitted */ }

Builder to enable forwarding tracing events towards the fluentd server.

Type params

• F - Attributes formatter, determines how to compose fluent::Record.
• A - function that returns Fluentd wrter. Default is to create tcp socket towards 127.0.0.1:24224 with timeout of 1s.

Implementations

impl Builder

pub fn new(tag: &'static str) -> Self

Creates default configuration.

Params:

tag - Event category to send for each record.

impl<A: MakeWriter> Builder<NestedFmt, A>

pub fn flatten(self) -> Builder<FlattenFmt, A>

Configures to flatten span/metadata attributes within record. Instead of the default nesting behavior.

impl<F: FieldFormatter, A: MakeWriter> Builder<F, A>

pub fn with_writer<MW: MakeWriter>(self, writer: MW) -> Builder<F, MW>

Provides callback to get writer where to write records.

Normally fluentd server expects connection to be closed immediately upon sending records. hence created writer is dropped immediately upon writing being finished.

pub fn layer(self) -> Result<Layer<F, ThreadWorker>, Error>

Creates tracing layer.

Error can happen during creation of worker thread.
