Struct TraceFilterer 

pub struct TraceFilterer { /* private fields */ }

Applies trace-level filters derived from the agent’s /info endpoint configuration: filter_tags, filter_tags_regex, and ignore_resources.

Filtering is evaluated on the root span of each trace.

Implementations

impl TraceFilterer

pub fn new( filter_tags_require: &[String], filter_tags_reject: &[String], filter_tags_regex_require: &[String], filter_tags_regex_reject: &[String], ignore_resources: &[String], ) -> Self

Creates a new filterer from the agent’s /info configuration fields.

Invalid regex patterns are logged and skipped rather than causing an error.

pub fn with_empty_conf() -> Self

Creates a no-op filterer that keeps all traces.

pub fn filter_traces( &self, traces: &mut Vec<Vec<Span<impl TraceData>>>, ) -> usize

Removes traces that fail filter checks in-place. Returns the number of traces dropped.

pub fn should_drop<'a>(&self, root_span: &'a impl Span<'a>) -> bool

Checks if the trace with root span root_span should be dropped based on filter configuration.

Applies a subset of trace normalization logic from libdd-trace-normalization before checking.
