}

Error type for the UpdateCachePolicyError operation.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

AccessDenied(AccessDenied)

Access denied.

CachePolicyAlreadyExists(CachePolicyAlreadyExists)

A cache policy with this name already exists. You must provide a unique name. To modify an existing cache policy, use UpdateCachePolicy.

IllegalUpdate(IllegalUpdate)

The update contains modifications that are not allowed.

InconsistentQuantities(InconsistentQuantities)

The value of Quantity and the size of Items don't match.

InvalidArgument(InvalidArgument)

An argument is invalid.

InvalidIfMatchVersion(InvalidIfMatchVersion)

The If-Match version is missing or not valid.

NoSuchCachePolicy(NoSuchCachePolicy)

The cache policy does not exist.

PreconditionFailed(PreconditionFailed)

The precondition in one or more of the request fields evaluated to false.

TooManyCookiesInCachePolicy(TooManyCookiesInCachePolicy)

The number of cookies in the cache policy exceeds the maximum. For more information, see Quotas (formerly known as limits) in the Amazon CloudFront Developer Guide.

TooManyHeadersInCachePolicy(TooManyHeadersInCachePolicy)

The number of headers in the cache policy exceeds the maximum. For more information, see Quotas (formerly known as limits) in the Amazon CloudFront Developer Guide.

TooManyQueryStringsInCachePolicy(TooManyQueryStringsInCachePolicy)

The number of query strings in the cache policy exceeds the maximum. For more information, see Quotas (formerly known as limits) in the Amazon CloudFront Developer Guide.

Unhandled(Unhandled)

👎Deprecated: Matching Unhandled directly is not forwards compatible. Instead, match using a variable wildcard pattern and check .code():    err if err.code() == Some("SpecificExceptionCode") => { /* handle the error */ } See ProvideErrorMetadata for what information is available for the error.

An unexpected error occurred (e.g., invalid JSON returned by the service or an unknown error code).
