Struct CallbackContext 

#[non_exhaustive]
pub struct CallbackContext {
    pub timeout: Option<Instant>,
    pub version: u32,
    pub refresh_token: Option<String>,
    pub idp_info: Option<IdpServerInfo>,
}

CallbackContext contains the information necessary to perform the human or machine flow in a function. The driver passes ownership of this struct to the Callback function.

use mongodb::{error::Error, Client, options::{ClientOptions, oidc::{Callback, CallbackContext, IdpServerResponse}}};
use std::time::{Duration, Instant};
use futures::future::FutureExt;
async fn do_human_flow(c: CallbackContext) -> Result<(String, Option<Instant>, Option<String>), Error> {
  // Do the human flow here see: https://auth0.com/docs/authenticate/login/oidc-conformant-authentication/oidc-adoption-auth-code-flow
  Ok(("some_access_token".to_string(), Some(Instant::now() + Duration::from_secs(60 * 60 * 12)), Some("some_refresh_token".to_string())))
}

async fn setup_client() -> Result<Client, Error> {
    let mut opts =
    ClientOptions::parse("mongodb://localhost:27017,localhost:27018/admin?authSource=admin&authMechanism=MONGODB-OIDC").await?;
    opts.credential.as_mut().unwrap().oidc_callback =
        Callback::human(move |c: CallbackContext| {
        async move {
            let (access_token, expires, refresh_token) = do_human_flow(c).await?;
            Ok(IdpServerResponse::builder().access_token(access_token).expires(expires).refresh_token(refresh_token).build())
        }.boxed()
    });
    Client::with_options(opts)
}

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

timeout: Option<Instant>

The time in the future when the function should return an error if it it has not completed.

version: u32

The version of the function API that the driver is using.

refresh_token: Option<String>

The refresh token that the driver has stored in the cache, which may not exist.

idp_info: Option<IdpServerInfo>

The information necessary to locate and authorize with an OIDC server.

Implementations

impl CallbackContext

pub fn builder() -> CallbackContextBuilder<((), (), (), ())>

Create a builder for building CallbackContext. On the builder, call .timeout(...)(optional), .version(...)(optional), .refresh_token(...)(optional), .idp_info(...)(optional) to set the values of the fields. Finally, call .build() to create the instance of CallbackContext.

Trait Implementations

impl Clone for CallbackContext

fn clone(&self) -> CallbackContext

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CallbackContext

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.
