Struct aws_sdk_dynamodb::client::customize::CustomizableOperation

pub struct CustomizableOperation<T, E, B> { /* private fields */ }

CustomizableOperation allows for configuring a single operation invocation before it is sent.

Implementations

impl<T, E, B> CustomizableOperation<T, E, B>

pub fn interceptor(self, interceptor: impl Intercept + 'static) -> Self

Adds an interceptor that runs at specific stages of the request execution pipeline.

Note that interceptors can also be added to CustomizableOperation by config_override, map_request, and mutate_request (the last two are implemented via interceptors under the hood). The order in which those user-specified operation interceptors are invoked should not be relied upon as it is an implementation detail.

pub fn map_request<F, MapE>(self, f: F) -> Self

where F: Fn(HttpRequest) -> Result<HttpRequest, MapE> + Send + Sync + 'static, MapE: Error + Send + Sync + 'static,

Allows for customizing the operation’s request.

pub fn mutate_request<F>(self, f: F) -> Self

where F: Fn(&mut HttpRequest) + Send + Sync + 'static,

Convenience for map_request where infallible direct mutation of request is acceptable.

pub fn config_override(self, config_override: impl Into<Builder>) -> Self

Overrides config for a single operation invocation.

config_override is applied to the operation configuration level. The fields in the builder that are Some override those applied to the service configuration level. For instance,

Config A	overridden by Config B	= Config C
field_1: None,	field_1: Some(v2),	field_1: Some(v2),
field_2: Some(v1),	field_2: Some(v2),	field_2: Some(v2),
field_3: Some(v1),	field_3: None,	field_3: Some(v1),

pub async fn send(self) -> Result<T, SdkError<E, HttpResponse>>

where E: Error + Send + Sync + 'static, B: CustomizableSend<T, E>,

Sends the request and returns the response.
