Struct aws_sdk_appsync::operation::evaluate_mapping_template::builders::EvaluateMappingTemplateFluentBuilder

pub struct EvaluateMappingTemplateFluentBuilder { /* private fields */ }

Fluent builder constructing a request to EvaluateMappingTemplate.

Evaluates a given template and returns the response. The mapping template can be a request or response template.

Request templates take the incoming request after a GraphQL operation is parsed and convert it into a request configuration for the selected data source operation. Response templates interpret responses from the data source and map it to the shape of the GraphQL field output type.

Mapping templates are written in the Apache Velocity Template Language (VTL).

Implementations

impl EvaluateMappingTemplateFluentBuilder

pub fn as_input(&self) -> &EvaluateMappingTemplateInputBuilder

Access the EvaluateMappingTemplate as a reference.

pub async fn send( self ) -> Result<EvaluateMappingTemplateOutput, SdkError<EvaluateMappingTemplateError, HttpResponse>>

Sends the request and returns the response.

If an error occurs, an SdkError will be returned with additional details that can be matched against.

By default, any retryable failures will be retried twice. Retry behavior is configurable with the RetryConfig, which can be set when configuring the client.

pub async fn customize( self ) -> Result<CustomizableOperation<EvaluateMappingTemplateOutput, EvaluateMappingTemplateError>, SdkError<EvaluateMappingTemplateError>>

Consumes this builder, creating a customizable operation that can be modified before being sent.

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

The mapping template; this can be a request or response template. A template is required for this action.

pub fn set_template(self, input: Option<String>) -> Self

The mapping template; this can be a request or response template. A template is required for this action.

pub fn get_template(&self) -> &Option<String>

The mapping template; this can be a request or response template. A template is required for this action.

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

The map that holds all of the contextual information for your resolver invocation. A context is required for this action.

pub fn set_context(self, input: Option<String>) -> Self

The map that holds all of the contextual information for your resolver invocation. A context is required for this action.

pub fn get_context(&self) -> &Option<String>

The map that holds all of the contextual information for your resolver invocation. A context is required for this action.
