Struct aws_sdk_cloudfront::types::CachePolicyConfig

#[non_exhaustive]
pub struct CachePolicyConfig {
    pub comment: Option<String>,
    pub name: String,
    pub default_ttl: Option<i64>,
    pub max_ttl: Option<i64>,
    pub min_ttl: i64,
    pub parameters_in_cache_key_and_forwarded_to_origin: Option<ParametersInCacheKeyAndForwardedToOrigin>,
}

A cache policy configuration.

This configuration determines the following:

• The values that CloudFront includes in the cache key. These values can include HTTP headers, cookies, and URL query strings. CloudFront uses the cache key to find an object in its cache that it can return to the viewer.

• The default, minimum, and maximum time to live (TTL) values that you want objects to stay in the CloudFront cache.

The headers, cookies, and query strings that are included in the cache key are also included in requests that CloudFront sends to the origin. CloudFront sends a request when it can't find a valid object in its cache that matches the request's cache key. If you want to send values to the origin but not include them in the cache key, use OriginRequestPolicy.

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.

comment: Option<String>

A comment to describe the cache policy. The comment cannot be longer than 128 characters.

name: String

A unique name to identify the cache policy.

default_ttl: Option<i64>

The default amount of time, in seconds, that you want objects to stay in the CloudFront cache before CloudFront sends another request to the origin to see if the object has been updated. CloudFront uses this value as the object's time to live (TTL) only when the origin does not send Cache-Control or Expires headers with the object. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.

The default value for this field is 86400 seconds (one day). If the value of MinTTL is more than 86400 seconds, then the default value for this field is the same as the value of MinTTL.

max_ttl: Option<i64>

The maximum amount of time, in seconds, that objects stay in the CloudFront cache before CloudFront sends another request to the origin to see if the object has been updated. CloudFront uses this value only when the origin sends Cache-Control or Expires headers with the object. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.

The default value for this field is 31536000 seconds (one year). If the value of MinTTL or DefaultTTL is more than 31536000 seconds, then the default value for this field is the same as the value of DefaultTTL.

min_ttl: i64

The minimum amount of time, in seconds, that you want objects to stay in the CloudFront cache before CloudFront sends another request to the origin to see if the object has been updated. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.

parameters_in_cache_key_and_forwarded_to_origin: Option<ParametersInCacheKeyAndForwardedToOrigin>

The HTTP headers, cookies, and URL query strings to include in the cache key. The values included in the cache key are also included in requests that CloudFront sends to the origin.

Implementations

impl CachePolicyConfig

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

A comment to describe the cache policy. The comment cannot be longer than 128 characters.

pub fn name(&self) -> &str

A unique name to identify the cache policy.

pub fn default_ttl(&self) -> Option<i64>

The default amount of time, in seconds, that you want objects to stay in the CloudFront cache before CloudFront sends another request to the origin to see if the object has been updated. CloudFront uses this value as the object's time to live (TTL) only when the origin does not send Cache-Control or Expires headers with the object. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.

The default value for this field is 86400 seconds (one day). If the value of MinTTL is more than 86400 seconds, then the default value for this field is the same as the value of MinTTL.

pub fn max_ttl(&self) -> Option<i64>

The maximum amount of time, in seconds, that objects stay in the CloudFront cache before CloudFront sends another request to the origin to see if the object has been updated. CloudFront uses this value only when the origin sends Cache-Control or Expires headers with the object. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.

The default value for this field is 31536000 seconds (one year). If the value of MinTTL or DefaultTTL is more than 31536000 seconds, then the default value for this field is the same as the value of DefaultTTL.

pub fn min_ttl(&self) -> i64

The minimum amount of time, in seconds, that you want objects to stay in the CloudFront cache before CloudFront sends another request to the origin to see if the object has been updated. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.

pub fn parameters_in_cache_key_and_forwarded_to_origin( &self ) -> Option<&ParametersInCacheKeyAndForwardedToOrigin>

The HTTP headers, cookies, and URL query strings to include in the cache key. The values included in the cache key are also included in requests that CloudFront sends to the origin.

impl CachePolicyConfig

pub fn builder() -> CachePolicyConfigBuilder

Creates a new builder-style object to manufacture CachePolicyConfig.

Trait Implementations

impl Clone for CachePolicyConfig

fn clone(&self) -> CachePolicyConfig

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CachePolicyConfig

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

Formats the value using the given formatter.

impl PartialEq for CachePolicyConfig

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

This method tests for self and other values to be equal, and is used by ==.

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

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