Struct RlgLayer 

pub struct RlgLayer { /* private fields */ }

Tower [Layer] that wraps a service with rlg request logging.

Build with RlgLayer::new and the fluent setters. Cheap to clone — internal state is a couple of small fields.

Implementations

impl RlgLayer

pub fn new() -> Self

Construct a new layer with the default configuration: level INFO, format Logfmt, component "rlg-tower", no trace-header extraction.

pub const fn level(self, level: LogLevel) -> Self

Override the level emitted for every record.

pub const fn format(self, format: LogFormat) -> Self

Override the wire format.

pub const fn component(self, component: &'static str) -> Self

Override the component attribute. Useful when multiple services share a process and you want to distinguish their access logs.

pub const fn header(self, name: &'static str) -> Self

Configure a request header to extract as the trace_id attribute. The common picks are traceparent (W3C trace-context) or x-b3-traceid (Zipkin B3).
