Struct JsonRenderer 

pub struct JsonRenderer<W: Write> { /* private fields */ }

JSON renderer — owns stdout exclusively in JSON mode.

Each call writes EXACTLY one serde_json document followed by a single \n and flushes the underlying writer. Multiple invocations of the binary therefore stream as NDJSON when concatenated.

Implementations

impl JsonRenderer<Stdout>

pub fn stdout() -> Self

Construct a renderer that writes to the process stdout handle.

impl<W: Write> JsonRenderer<W>

pub fn new(writer: W) -> Self

Construct a renderer wrapping any Write implementation.
