use std::fs;

use rocket_error_stack::{Result, StatusCodeReport};

#[derive(Debug)]
struct SomeError(pub Status);

impl StatusCodeReport for SomeError {
  fn status(&self) -> Status {
      self.0
  }
}

impl fmt::Display for SomeError {
    fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result {
        f.write_str("Error during request")
    }
}

impl Context for SomeError {}

#[get("/")]
fn get() -> Result<(), SomeError> {
  fs::read_to_string("nonexistent")
    .into_report()
    .attach_printable("Something went wrong!")
    .change_context(SomeError(Status::InternalServerError))?;
