    .with_webpki_roots()
    .https_only()
    .enable_http1()
    .enable_http2()
    .build();

fn base_url() -> String {
    // ...
}

#[derive(Debug)]

        let request = context.request_mut();
        let uri = format!("{}{}", base_url(), request.uri().path());
        *request.uri_mut() = uri.parse()?;

Interceptors targeted at a certain stage are executed according to the pre-defined priority. The SDK provides a default set of interceptors. An interceptor configured by this method will run after those default interceptors.

Examples

use aws_smithy_runtime_api::client::interceptors::context::phase::BeforeTransmit;
use aws_smithy_runtime_api::client::interceptors::{Interceptor, InterceptorContext, SharedInterceptor};
use aws_smithy_types::config_bag::ConfigBag;
use aws_sdk_dynamodb::config::{Builder, Config};

fn base_url() -> String {

    impl Interceptor for UriModifierInterceptor {
        fn modify_before_signing(
            &self,
            context: &mut InterceptorContext<BeforeTransmit>,
            _cfg: &mut ConfigBag,
        ) -> Result<(), aws_smithy_runtime_api::client::interceptors::BoxError> {

The invocation ID generator generates ID values for the amz-sdk-invocation-id header. By default, this will be a random UUID. Overriding it may be useful in tests that examine the HTTP request and need to be deterministic.

pub fn set_invocation_id_generator( &mut self, gen: Option<SharedInvocationIdGenerator> ) -> &mut Self

Overrides the default invocation ID generator.

The invocation ID generator generates ID values for the amz-sdk-invocation-id header. By default, this will be a random UUID. Overriding it may be useful in tests that examine the HTTP request and need to be deterministic.

pub fn endpoint_url(self, endpoint_url: impl Into<String>) -> Self

pub fn set_endpoint_url(&mut self, endpoint_url: Option<String>) -> &mut Self

Sets the endpoint URL used to communicate with this service Note: this is used in combination with other endpoint rules, e.g. an API that applies a host-label prefix will be prefixed onto this URL. To fully override the endpoint resolver, use Builder::endpoint_resolver.

pub fn use_dual_stack(self, use_dual_stack: impl Into<bool>) -> Self
