Struct `NoContent`

pub struct NoContent;

An empty response with 204 No Content status.

Due to historical and implementation reasons, the IntoResponse implementation of () (unit type) returns an empty response with 200 StatusCode::OK status. If you specifically want a 204 StatusCode::NO_CONTENT status, you can use either StatusCode type directly, or this shortcut struct for self-documentation.

use axum::{extract::Path, response::NoContent};

async fn delete_user(Path(user): Path<String>) -> Result<NoContent, String> {
    // ...access database...
# drop(user);
    Ok(NoContent)
}
