Struct ExternallyManaged 

pub struct ExternallyManaged { /* private fields */ }

A struct that manages access tokens by utilizing a user-provided refresh function.

The ExternallyManaged struct allows users to define custom logic for fetching or refreshing access tokens.

Implementations

impl ExternallyManaged

pub fn new( refresh_function: impl Fn(AuthServer) -> Pin<Box<dyn Future<Output = Result<String, Box<dyn Error + Send + Sync>>> + Send>> + Send + Sync + 'static, ) -> Self

Creates a new ExternallyManaged instance from a RefreshFunction.

Consider using ExternallyManaged::from_async, and ExternallyManaged::from_sync, if they better fit your use case.

Arguments

• refresh_function - A function or closure that asynchronously refreshes a token.

Example

use qcs_api_client_common::configuration::{AuthServer, ExternallyManaged, TokenError};
use std::future::Future;
use std::pin::Pin;
use std::boxed::Box;
use std::error::Error;

async fn example_refresh_function(_auth_server: AuthServer) -> Result<String, Box<dyn Error
+ Send + Sync>> {
    Ok("new_token_value".to_string())
}
let token_manager = ExternallyManaged::new(|auth_server| Box::pin(example_refresh_function(auth_server)));

pub fn from_async<F, Fut>(refresh_function: F) -> Self

where F: Fn(AuthServer) -> Fut + Send + Sync + 'static, Fut: Future<Output = Result<String, Box<dyn Error + Send + Sync>>> + Send + 'static,

Constructs a new ExternallyManaged instance using an async function or closure.

This method simplifies the creation of the ExternallyManaged instance by handling the boxing and pinning of the future internally.

Arguments

• refresh_function - An async function or closure that returns a Future which, when awaited, produces a Result<String, TokenError>.

Example

use qcs_api_client_common::configuration::{AuthServer, ExternallyManaged, TokenError};
use tokio::runtime::Runtime;
use std::error::Error;

async fn example_refresh_function(_auth_server: AuthServer) -> Result<String, Box<dyn Error
+ Send + Sync>> {
    Ok("new_token_value".to_string())
}

let token_manager = ExternallyManaged::from_async(example_refresh_function);

let rt = Runtime::new().unwrap();
rt.block_on(async {
    match token_manager.request_access_token(&AuthServer::default()).await {
        Ok(token) => println!("Token: {}", token),
        Err(e) => println!("Failed to refresh token: {:?}", e),
    }
});

pub fn from_sync( refresh_function: impl Fn(AuthServer) -> Result<String, Box<dyn Error + Send + Sync>> + Send + Sync + 'static, ) -> Self

Constructs a new ExternallyManaged instance using a synchronous function.

The synchronous function is wrapped in an async block to fit the expected signature.

Arguments

• refresh_function - A synchronous function that returns a Result<String, TokenError>.

Example

use qcs_api_client_common::configuration::{AuthServer, ExternallyManaged, TokenError};
use tokio::runtime::Runtime;
use std::error::Error;

fn example_sync_refresh_function(_auth_server: AuthServer) -> Result<String, Box<dyn Error
+ Send + Sync>> {
    Ok("sync_token_value".to_string())
}

let token_manager = ExternallyManaged::from_sync(example_sync_refresh_function);

let rt = Runtime::new().unwrap();
rt.block_on(async {
    match token_manager.request_access_token(&AuthServer::default()).await {
        Ok(token) => println!("Token: {}", token),
        Err(e) => println!("Failed to refresh token: {:?}", e),
    }
});

pub async fn request_access_token( &self, auth_server: &AuthServer, ) -> Result<String, Box<dyn Error + Send + Sync>>

Request an updated access token using the provided refresh function.

Errors

Errors are propagated from the refresh function.
