}Expand description
Header manipulation ops (DW-028). Applied in ONE deterministic
order regardless of YAML key order: set (replace all values of the
name with one value), then add (append one value, keeping any
existing values), then rename (move every value of from to
to), then remove (drop every value of the name) — so remove
can clean up what earlier ops placed, and rename sees both
upstream and just-set values. Maps iterate in sorted key order
(BTreeMap), making multi-entry application deterministic.
The block runs after hop-by-hop stripping on the request side and
before the gateway’s own policy stamps on the response side;
framing and hop-by-hop header names are rejected by validation in
BOTH directions (see dataplane::transforms module docs for the
rationale).
Fields§
§set: BTreeMap<String, String>Replace every value of the header name with this single value (an absent name is inserted).
add: BTreeMap<String, String>Append one value to the header name, keeping any existing values (the way to build multi-value headers deterministically).
remove: Vec<String>Drop every value of these header names.
rename: BTreeMap<String, String>Relabel every value of from onto to (existing to values
are kept; the renamed values append after them). One entry per
source name; a from == to entry is rejected by validation.
