Struct JsonlHookSink 

pub struct JsonlHookSink { /* private fields */ }

A HookSink that appends each event as a JSON line to a file.

The file is created (along with any missing parent directories) on the first emitted event. Each line is a JSON object of the form {"at": "<ISO 8601 timestamp>", "event": {...}}.

Concurrent emit calls serialize on an internal mutex so that each JSON event is written and flushed as a complete line; without that lock, overlapping write_all calls can interleave partial lines and corrupt the JSONL log (see issue #4739).

Implementations

impl JsonlHookSink

pub fn new(path: PathBuf) -> Self

Create a new sink that writes to the file at path.

Parent directories are created lazily on the first HookSink::emit call.
