Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

type_name: Option<String>

The resolver type name.

field_name: Option<String>

The resolver field name.

data_source_name: Option<String>

The resolver data source name.

resolver_arn: Option<String>

The resolver Amazon Resource Name (ARN).

request_mapping_template: Option<String>

The request mapping template.

response_mapping_template: Option<String>

The response mapping template.

kind: Option<ResolverKind>

The resolver type.

• UNIT: A UNIT resolver type. A UNIT resolver is the default resolver type. You can use a UNIT resolver to run a GraphQL query against a single data source.

• PIPELINE: A PIPELINE resolver type. You can use a PIPELINE resolver to invoke a series of Function objects in a serial manner. You can use a pipeline resolver to run a GraphQL query against multiple data sources.

pipeline_config: Option<PipelineConfig>

The PipelineConfig.

sync_config: Option<SyncConfig>

The SyncConfig for a resolver attached to a versioned data source.

caching_config: Option<CachingConfig>

The caching configuration for the resolver.

max_batch_size: i32

The maximum batching size for a resolver.

runtime: Option<AppSyncRuntime>

Describes a runtime used by an Amazon Web Services AppSync pipeline resolver or Amazon Web Services AppSync function. Specifies the name and version of the runtime to use. Note that if a runtime is specified, code must also be specified.

code: Option<String>

The resolver code that contains the request and response functions. When code is used, the runtime is required. The runtime value must be APPSYNC_JS.

metrics_config: Option<ResolverLevelMetricsConfig>

Enables or disables enhanced resolver metrics for specified resolvers. Note that metricsConfig won't be used unless the resolverLevelMetricsBehavior value is set to PER_RESOLVER_METRICS. If the resolverLevelMetricsBehavior is set to FULL_REQUEST_RESOLVER_METRICS instead, metricsConfig will be ignored. However, you can still set its value.

metricsConfig can be ENABLED or DISABLED.

pub fn caching_config(&self) -> Option<&CachingConfig>

The caching configuration for the resolver.

pub fn max_batch_size(&self) -> i32

The maximum batching size for a resolver.

pub fn runtime(&self) -> Option<&AppSyncRuntime>

If the resolverLevelMetricsBehavior is set to FULL_REQUEST_RESOLVER_METRICS instead, metricsConfig will be ignored. However, you can still set its value.

metricsConfig can be ENABLED or DISABLED.

impl Resolver

pub fn builder() -> ResolverBuilder

Creates a new builder-style object to manufacture Resolver.

Trait Implementations

impl Clone for Resolver

fn clone(&self) -> Resolver

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Resolver

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Resolver

fn eq(&self, other: &Resolver) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
