Struct AsyncHttpHeaderInjector 

Source 
pub struct AsyncHttpHeaderInjector { /* private fields */ }
Expand description

Async HTTP header injector that can await external state (for example token refresh) before mutating outbound request headers.

Implementations§

Source§

impl AsyncHttpHeaderInjector

Source

pub fn new<F>(injector: F) -> Self
where F: for<'a> Fn(&'a mut HeaderMap) -> Pin<Box<dyn Future<Output = HttpResult<()>> + Send + 'a>> + Send + Sync + 'static,

Creates an async header injector from a callback.

§Parameters
  • injector: Async callback that mutates HeaderMap and may fail.
§Returns

New AsyncHttpHeaderInjector.

Source

pub async fn apply(&self, headers: &mut HeaderMap) -> HttpResult<()>

Applies this injector to headers.

§Parameters
  • headers: Header map to mutate.
§Returns

Ok(()) on success.

§Errors

Propagates callback-provided crate::HttpError.
