Struct roa_core::Status

pub struct Status {
    pub status_code: StatusCode,
    pub message: String,
    pub expose: bool,
}

The Status of roa.

Fields

status_code: StatusCode

StatusCode will be responded to client if Error is thrown by the top middleware.

Example

use roa_core::{App, Context, Next, Result, MiddlewareExt, throw};
use roa_core::http::StatusCode;

let app = App::new().gate(gate).end(end);
async fn gate(ctx: &mut Context, next: Next<'_>) -> Result {
    ctx.resp.status = StatusCode::OK;
    next.await // not caught
}

async fn end(ctx: &mut Context) -> Result {
    throw!(StatusCode::IM_A_TEAPOT, "I'm a teapot!"); // throw
    unreachable!()
}

message: String

Data will be written to response body if self.expose is true. StatusCode will be responded to client if Error is thrown by the top middleware.

Example

use roa_core::{App, Context, Result, Status};
use roa_core::http::StatusCode;

let app = App::new().end(end);

async fn end(ctx: &mut Context) -> Result {
    Err(Status::new(StatusCode::IM_A_TEAPOT, "I'm a teapot!", false)) // message won't be exposed to user.
}

expose: bool

if message exposed.
