Struct tracing_actix_web_mozlog::MozLogFormatLayer

pub struct MozLogFormatLayer<W: MakeWriter + 'static> { /* private fields */ }

This layer is exclusively concerned with formatting information using the MozLog format. It relies on the upstream crate::JsonStorageLayer to get access to the fields attached to each span.

Example

use tracing_actix_web_mozlog::{JsonStorageLayer, MozLogFormatLayer};
use tracing_subscriber::layer::SubscriberExt;
let subscriber = tracing_subscriber::registry()
    .with(JsonStorageLayer)
    .with(MozLogFormatLayer::new("service-name", std::io::stdout));

Implementations

impl<W: MakeWriter + 'static> MozLogFormatLayer<W>

pub fn new<S: AsRef<str>>(name: S, make_writer: W) -> Self

Create a new moz log subscriber.

Trait Implementations

impl<S, W> Layer<S> for MozLogFormatLayer<W> where
    S: Subscriber + for<'a> LookupSpan<'a>,
    W: MakeWriter + 'static, 

fn on_event(&self, event: &Event<'_>, ctx: Context<'_, S>)

Notifies this layer that an event has occurred.

fn register_callsite(&self, metadata: &'static Metadata<'static>) -> Interest

Registers a new callsite with this layer, returning whether or not the layer is interested in being notified about the callsite, similarly to Subscriber::register_callsite.

fn enabled(&self, metadata: &Metadata<'_>, ctx: Context<'_, S>) -> bool

Returns true if this layer is interested in a span or event with the given metadata in the current Context, similarly to Subscriber::enabled.

fn new_span(&self, attrs: &Attributes<'_>, id: &Id, ctx: Context<'_, S>)

Notifies this layer that a new span was constructed with the given Attributes and Id.

fn on_record(&self, _span: &Id, _values: &Record<'_>, _ctx: Context<'_, S>)

Notifies this layer that a span with the given Id recorded the given values.

fn on_follows_from(&self, _span: &Id, _follows: &Id, _ctx: Context<'_, S>)

Notifies this layer that a span with the ID span recorded that it follows from the span with the ID follows.

fn on_enter(&self, _id: &Id, _ctx: Context<'_, S>)

Notifies this layer that a span with the given ID was entered.

fn on_exit(&self, _id: &Id, _ctx: Context<'_, S>)

Notifies this layer that the span with the given ID was exited.

fn on_close(&self, _id: Id, _ctx: Context<'_, S>)

Notifies this layer that the span with the given ID has been closed.

fn on_id_change(&self, _old: &Id, _new: &Id, _ctx: Context<'_, S>)

Notifies this layer that a span ID has been cloned, and that the subscriber returned a different ID.

fn and_then<L>(self, layer: L) -> Layered<L, Self, S> where
    L: Layer<S>, 

Composes this layer around the given Layer, returning a Layered struct implementing Layer.

fn with_subscriber(self, inner: S) -> Layered<Self, S, S>

Composes this Layer with the given Subscriber, returning a Layered struct that implements Subscriber.
