Struct tracing_layer_slack::SlackLayerBuilder

pub struct SlackLayerBuilder { /* fields omitted */ }

A builder for creating a Slack layer.

The layer requires a regex for selecting events to be sent to Slack 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 Slack configuration that defaults to searching in the local environment variables.

Implementations

impl SlackLayerBuilder

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 Slack.

Filter type semantics:

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

pub fn slack_config(self, config: SlackConfig) -> Self

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

pub fn build(self) -> (SlackLayer, SlackBackgroundWorker)

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