Struct ServerPropagatorConfig 

#[non_exhaustive]
pub struct ServerPropagatorConfig {
    pub metadata_predicate: Option<Arc<dyn Fn(&[String], &str) -> bool + Send + Sync>>,
    pub header_predicate: Option<Arc<dyn Fn(&str) -> bool + Send + Sync>>,
}

Configuration for ServerPropagator.

Both predicates are optional — sensible defaults are used when None.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

metadata_predicate: Option<Arc<dyn Fn(&[String], &str) -> bool + Send + Sync>>

Determines which payload metadata keys are propagated.

Default: propagate keys whose name matches a client-requested extension URI.

header_predicate: Option<Arc<dyn Fn(&str) -> bool + Send + Sync>>

Determines which request headers are propagated.

Default: propagate only the x-a2a-extensions header.
