pub struct Stackdriver<W = fn() -> Stdout> where
    W: MakeWriter,  { /* fields omitted */ }

A tracing adapater for stackdriver

Methods

impl Stackdriver

pub fn new() -> Self

Initialize the Stackdriver Layer with the default writer (std::io::Stdout)

impl<W> Stackdriver<W> where
    W: MakeWriter, 

pub fn with_writer(writer: W) -> Self

Initialize the Stackdriver Layer with a custom writer

Trait Implementations

impl Default for Stackdriver

fn default() -> Self

Returns the "default value" for a type.

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

fn new_span(&self, attributes: &Attributes, id: &Id, context: Context<S>)

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

fn on_event(&self, event: &Event, context: 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 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].
