Crate nxd_plugin_protocol

Modules§

EventSequencer
ProgressBatcher
ProgressReporter: Unlimited timed flushes so multi-minute builds keep streaming.
SensitiveTextRedactor: Language-neutral safe_message policy helper for bundled Rust providers and core.

MAX_EVENTS: Hard cap on retained apply events. Progress is streamed/logged; only the terminal Completed event must be retained for confidential outputs.
MAX_MESSAGE_BYTES
MAX_PROGRESS_MESSAGE_BYTES: Progress/detail body payloads (DATA frames). Smaller than MAX_MESSAGE_BYTES so one event stays cheap to buffer on the wire.
MAX_STATUS_MESSAGE_BYTES: gRPC status/trailers live in HTTP/2 HEADERS frames. Keep well under the default SETTINGS_MAX_HEADER_LIST_SIZE (~16–64 KiB) so large Nix stderr cannot GOAWAY the plugin connection with header_list_way_too_large.
PROTOCOL_VERSION

redact_sensitive_text
schema_digest: Stable content digest for provider resource schema bytes.
truncate_progress_message: Truncate a progress/detail message for ApplyResponse DATA frames. Progress chunks already batch recent lines; keep the head of each chunk.
truncate_status_message: Truncate a human message for gRPC Status / trailers (HEADERS).
