Struct tracing_layer_core::layer::WebhookLayerBuilder

pub struct WebhookLayerBuilder<C: Config, F: WebhookMessageFactory> { /* private fields */ }

A builder for creating a webhook layer.

The layer requires a regex for selecting events to be sent to Discord by their target. Specifying no filter (e.g. “.*”) will cause an explosion in the number of messages observed by the layer.

Several methods expose initialization of optional filtering mechanisms, along with Discord configuration that defaults to searching in the local environment variables.

Implementations

impl<C: Config, F: WebhookMessageFactory> WebhookLayerBuilder<C, F>

pub fn message_filters(self, filters: EventFilters) -> Self

Filter events by their message.

Filter type semantics:

• Positive: Exclude an event if the message MATCHES a given regex, and
• Negative: Exclude an event if the message does NOT MATCH a given regex.

pub fn event_by_field_filters(self, filters: EventFilters) -> Self

Filter events by fields.

Filter type semantics:

• Positive: Exclude the event if its key MATCHES a given regex.
• Negative: Exclude the event if its key does NOT MATCH a given regex.

pub fn field_exclusion_filters(self, filters: Vec<Regex>) -> Self

Filter fields of events from being sent to Discord.

Filter type semantics:

• Positive: Exclude event fields if the field’s key MATCHES any provided regular expressions.

pub fn config(self, config: C) -> Self

Configure the layer’s connection to the Discord Webhook API.

pub fn level_filters(self, level_filters: String) -> Self

Configure which levels of events to send to Discord.

pub fn build(self) -> (WebhookLayer<C, F>, BackgroundWorker)

Create a DiscordLayer and its corresponding background worker to (async) send the messages.
