Struct aws_sdk_transcribe::middleware::DefaultMiddleware

#[non_exhaustive]
pub struct DefaultMiddleware;

AWS Middleware Stack

This implements the middleware stack for this service. It will:

1. Load credentials asynchronously into the property bag
2. Sign the request with SigV4
3. Resolve an Endpoint for the request
4. Add a user agent to the request

Implementations

impl DefaultMiddleware

pub fn new() -> Self

Create a new DefaultMiddleware stack

Note: DefaultMiddleware holds no state.
