pub fn render_json<R: Serialize>(rows: &[R]) -> Result<String, RenderError>Expand description
Render rows as a pretty-printed JSON array (one element per
row, two-space indent, trailing newline).
§Errors
RenderError::Json when any row fails to serialise — typical
causes are non-string Map keys or non-finite floats. Always
programmer mistake; payload is a stringified serde_json::Error.
