Struct ResponseBodyTransform 

pub struct ResponseBodyTransform<F>
where
    F: Fn(Vec<u8>) -> Vec<u8> + Send + Sync,
{ /* private fields */ }

A response transformer that applies a function to the response body.

This is useful for content transformations like:

• Minification
• Pretty-printing
• Wrapping responses
• Filtering content

Example

// Wrap JSON responses in an envelope
let transformer = ResponseBodyTransform::new(|body| {
    format!(r#"{{"data": {}}}"#, String::from_utf8_lossy(&body)).into_bytes()
});

Implementations

impl<F> ResponseBodyTransform<F>

where F: Fn(Vec<u8>) -> Vec<u8> + Send + Sync,

pub fn new(transform_fn: F) -> Self

Create a new body transformer with the given function.

pub fn for_content_type(self, content_type: impl Into<String>) -> Self

Only apply transformation if the response content type starts with this value.

Trait Implementations

impl<F> ResponseInterceptor for ResponseBodyTransform<F>

where F: Fn(Vec<u8>) -> Vec<u8> + Send + Sync,

fn intercept<'a>( &'a self, _ctx: &'a ResponseInterceptorContext<'a>, response: Response, ) -> BoxFuture<'a, Response>

Process a response after the handler has executed.

fn name(&self) -> &'static str

Returns the interceptor name for debugging and logging.
