Struct CloudWatchLayer 

pub struct CloudWatchLayer<S, D, N = DefaultFields, E = Format<Full, ()>> { /* private fields */ }

An AWS Cloudwatch propagation layer.

Implementations

impl<S, D> CloudWatchLayer<S, D, DefaultFields, Format<Full, ()>>

where S: Subscriber + for<'span> LookupSpan<'span>, D: Dispatcher + 'static, Arc<D>: for<'writer> MakeWriter<'writer>,

pub fn new(dispatcher: Arc<D>) -> Self

impl<S, D, N, L, T> CloudWatchLayer<S, D, N, Format<L, T>>

where N: for<'writer> FormatFields<'writer> + 'static,

pub fn with_code_location(self, display: bool) -> Self

Configure to display line number and filename. Default true

pub fn with_target(self, display: bool) -> Self

Configure to display target module. Default false.

impl<S, D, N, E> CloudWatchLayer<S, D, N, E>

where S: Subscriber + for<'span> LookupSpan<'span>, D: Dispatcher + 'static, Arc<D>: for<'writer> MakeWriter<'writer>,

pub fn with_client<Client>( self, client: Client, export_config: ExportConfig, ) -> CloudWatchLayer<S, CloudWatchDispatcher, N, E>

where Client: CloudWatchClient + Send + Sync + 'static,

Set client.

pub fn with_fmt_layer<N2, E2, W>( self, fmt_layer: Layer<S, N2, E2, W>, ) -> CloudWatchLayer<S, D, N2, E2>

Set the fmt::Layer provided as an argument. You can control the log format for CloudWatch by setting a pre-configured fmt::Layer However, the specification of the writer will be overrided.

Trait Implementations

impl<S> Default for CloudWatchLayer<S, NoopDispatcher, DefaultFields, Format<Full, ()>>

where S: Subscriber + for<'span> LookupSpan<'span>,

fn default() -> Self

Returns the “default value” for a type.

impl<S, D, N, E> Layer<S> for CloudWatchLayer<S, D, N, E>

where S: Subscriber + for<'span> LookupSpan<'span>, D: Dispatcher + 'static, Arc<D>: for<'writer> MakeWriter<'writer>, N: for<'writer> FormatFields<'writer> + 'static, E: FormatEvent<S, N> + 'static,

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

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

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

Notifies this layer that an event has occurred.

fn on_register_dispatch(&self, collector: &Dispatch)

Performs late initialization when installing this layer as a Subscriber.

fn on_layer(&mut self, subscriber: &mut S)

Performs late initialization when attaching a Layer to a Subscriber.

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_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, id: &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 event_enabled(&self, event: &Event<'_>, ctx: Context<'_, S>) -> bool

Called before on_event, to determine if on_event should be called.

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

where L: Layer<S>, Self: Sized,

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

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

where Self: Sized,

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

fn with_filter<F>(self, filter: F) -> Filtered<Self, F, S>

where Self: Sized, F: Filter<S>,

Combines self with a Filter, returning a Filtered layer.

fn boxed(self) -> Box<dyn Layer<S> + Sync + Send>

where Self: Sized + Layer<S> + Send + Sync + 'static, S: Subscriber,

Erases the type of this Layer, returning a Boxed dyn Layer trait object.
