Trait IntoResponse 

pub trait IntoResponse: IntoResponseBounds {
    // Required method
    fn into_response(self) -> Response;
}

Trait for converting types into bot responses

Similar to skyzen’s Responder trait, this allows handlers to return various types that get converted to responses.

Example

// Return a string directly
async fn ping() -> &'static str {
    "Pong!"
}

// Return a formatted string
async fn greet(user: User) -> String {
    format!("Hello, {}!", user.name)
}

// Return Response for full control
async fn buttons() -> Response {
    Response::text("Click a button:")
        .with_components(vec![...])
}

Required Methods

fn into_response(self) -> Response

Convert this type into a bot response

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

fn into_response(self) -> Response

fn into_response(self) -> Response

impl<T, E> IntoResponse for Result<T, E>

where T: IntoResponse, E: Display + IntoResponseBounds,

Err is rendered to the user as Error: {e}.

Return Response directly when a handler needs to control what a failure looks like, or keep the error type’s Display user-facing.
