Struct DataMarkerExtractorRegistry 

pub struct DataMarkerExtractorRegistry { /* private fields */ }

Registry of marker extractors keyed by concrete message TypeId.

Registration happens before the capture tap is installed. Lookups use the concrete type behind &dyn Any, so the hot path avoids trying every extractor.

Implementations

impl DataMarkerExtractorRegistry

pub fn new() -> Self

Creates an empty extractor registry.

pub fn register<T: 'static>(&mut self, ex: Box<dyn DataMarkerExtractor>)

Registers ex as the marker extractor for T.

Replaces any previous extractor for T; callers should finish registration before sharing the registry with the capture path.

pub fn default_registry(classes: &[DataClass]) -> Self

Creates a registry containing builtin extractors for the enabled classes.

pub fn lookup(&self, msg: &dyn Any) -> Option<&dyn DataMarkerExtractor>

Returns the extractor registered for the concrete type behind msg.
