Struct CustomErrorResponse

#[non_exhaustive]
pub struct CustomErrorResponse {
    pub error_code: i32,
    pub response_page_path: Option<String>,
    pub response_code: Option<String>,
    pub error_caching_min_ttl: Option<i64>,
}

A complex type that controls:

• Whether CloudFront replaces HTTP status codes in the 4xx and 5xx range with custom error messages before returning the response to the viewer.

• How long CloudFront caches HTTP status codes in the 4xx and 5xx range.

For more information about custom error pages, see Customizing Error Responses in the Amazon CloudFront Developer Guide.

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.

error_code: i32

The HTTP status code for which you want to specify a custom error page and/or a caching duration.

response_page_path: Option<String>

The path to the custom error page that you want CloudFront to return to a viewer when your origin returns the HTTP status code specified by ErrorCode, for example, /4xx-errors/403-forbidden.html. If you want to store your objects and your custom error pages in different locations, your distribution must include a cache behavior for which the following is true:

• The value of PathPattern matches the path to your custom error messages. For example, suppose you saved custom error pages for 4xx errors in an Amazon S3 bucket in a directory named /4xx-errors. Your distribution must include a cache behavior for which the path pattern routes requests for your custom error pages to that location, for example, /4xx-errors/*.

• The value of TargetOriginId specifies the value of the ID element for the origin that contains your custom error pages.

If you specify a value for ResponsePagePath, you must also specify a value for ResponseCode.

We recommend that you store custom error pages in an Amazon S3 bucket. If you store custom error pages on an HTTP server and the server starts to return 5xx errors, CloudFront can't get the files that you want to return to viewers because the origin server is unavailable.

response_code: Option<String>

The HTTP status code that you want CloudFront to return to the viewer along with the custom error page. There are a variety of reasons that you might want CloudFront to return a status code different from the status code that your origin returned to CloudFront, for example:

• Some Internet devices (some firewalls and corporate proxies, for example) intercept HTTP 4xx and 5xx and prevent the response from being returned to the viewer. If you substitute 200, the response typically won't be intercepted.

• If you don't care about distinguishing among different client errors or server errors, you can specify 400 or 500 as the ResponseCode for all 4xx or 5xx errors.

• You might want to return a 200 status code (OK) and static website so your customers don't know that your website is down.

If you specify a value for ResponseCode, you must also specify a value for ResponsePagePath.

error_caching_min_ttl: Option<i64>

The minimum amount of time, in seconds, that you want CloudFront to cache the HTTP status code specified in ErrorCode. When this time period has elapsed, CloudFront queries your origin to see whether the problem that caused the error has been resolved and the requested object is now available.

Implementations

impl CustomErrorResponse

pub fn error_code(&self) -> i32

The HTTP status code for which you want to specify a custom error page and/or a caching duration.

pub fn response_page_path(&self) -> Option<&str>

The path to the custom error page that you want CloudFront to return to a viewer when your origin returns the HTTP status code specified by ErrorCode, for example, /4xx-errors/403-forbidden.html. If you want to store your objects and your custom error pages in different locations, your distribution must include a cache behavior for which the following is true:

If you specify a value for ResponsePagePath, you must also specify a value for ResponseCode.

impl CustomErrorResponse

pub fn builder() -> CustomErrorResponseBuilder

Creates a new builder-style object to manufacture CustomErrorResponse.

Trait Implementations

impl Clone for CustomErrorResponse

fn clone(&self) -> CustomErrorResponse

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CustomErrorResponse

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

Formats the value using the given formatter.

impl PartialEq for CustomErrorResponse

fn eq(&self, other: &CustomErrorResponse) -> 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.
