Struct OutputFormatter 

pub struct OutputFormatter { /* private fields */ }

Middleware that truncates tool output to a maximum character length.

Long tool outputs can consume excessive tokens in the context window. This middleware truncates text content items that exceed the limit.

Implementations

impl OutputFormatter

pub fn new(max_chars: usize) -> Self

Create a new output formatter with the given character limit.
