pub fn parse_context_query(spec: &str) -> Result<ContextQuerySpec, String>Expand description
Parse a --context-query spelling: name or
name($p = /ptr, $q = /ptr).
The plain-name form parses to an empty binding list, byte-identical in
meaning to the 1.5.0 feature. Errors are plain strings — this runs at
declaration time (CLI + schedule::validate) and at fire time, and both
surface the message verbatim.
Pointers must start with / (RFC 6901) and, because , and ) are
structural in this spelling, cannot contain either character. Keys that
need them can be reached by reshaping the connector payload.
