#[non_exhaustive]
pub struct InstanceMetadataOptionsRequest {

The metadata options for the instance.

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.

http_tokens: Option<HttpTokensState>

IMDSv2 uses token-backed sessions. Set the use of HTTP tokens to optional (in other words, set the use of IMDSv2 to optional) or required (in other words, set the use of IMDSv2 to required).

• optional - When IMDSv2 is optional, you can choose to retrieve instance metadata with or without a session token in your request. If you retrieve the IAM role credentials without a token, the IMDSv1 role credentials are returned. If you retrieve the IAM role credentials using a valid session token, the IMDSv2 role credentials are returned.

• required - When IMDSv2 is required, you must send a session token with any instance metadata retrieval requests. In this state, retrieving the IAM role credentials always returns IMDSv2 credentials; IMDSv1 credentials are not available.

Default: optional

http_put_response_hop_limit: Option<i32>

The desired HTTP PUT response hop limit for instance metadata requests. The larger the number, the further instance metadata requests can travel.

Default: 1

Possible values: Integers from 1 to 64

http_endpoint: Option<InstanceMetadataEndpointState>

Enables or disables the HTTP metadata endpoint on your instances.

If you specify a value of disabled, you cannot access your instance metadata.

Default: enabled

http_protocol_ipv6: Option<InstanceMetadataProtocolState>

Enables or disables the IPv6 endpoint for the instance metadata service.

instance_metadata_tags: Option<InstanceMetadataTagsState>

Set to enabled to allow access to instance tags from the instance metadata. Set to disabled to turn off access to instance tags from the instance metadata. For more information, see Work with instance tags using the instance metadata.

Default: disabled

impl InstanceMetadataOptionsRequest

pub fn http_tokens(&self) -> Option<&HttpTokensState>

IMDSv2 uses token-backed sessions. Set the use of HTTP tokens to optional (in other words, set the use of IMDSv2 to optional) or required (in other words, set the use of IMDSv2 to required).

• optional - When IMDSv2 is optional, you can choose to retrieve instance metadata with or without a session token in your request. If you retrieve the IAM role credentials without a token, the IMDSv1 role credentials are returned. If you retrieve the IAM role credentials using a valid session token, the IMDSv2 role credentials are returned.

Default: optional

pub fn http_put_response_hop_limit(&self) -> Option<i32>

The desired HTTP PUT response hop limit for instance metadata requests. The larger the number, the further instance metadata requests can travel.

Default: 1

Possible values: Integers from 1 to 64

pub fn http_endpoint(&self) -> Option<&InstanceMetadataEndpointState>

Enables or disables the HTTP metadata endpoint on your instances.

If you specify a value of disabled, you cannot access your instance metadata.

Default: enabled

pub fn http_protocol_ipv6(&self) -> Option<&InstanceMetadataProtocolState>

Enables or disables the IPv6 endpoint for the instance metadata service.

pub fn instance_metadata_tags(&self) -> Option<&InstanceMetadataTagsState>

Set to enabled to allow access to instance tags from the instance metadata. Set to disabled to turn off access to instance tags from the instance metadata. For more information, see Work with instance tags using the instance metadata.

Default: disabled

impl InstanceMetadataOptionsRequest

pub fn builder() -> InstanceMetadataOptionsRequestBuilder

Creates a new builder-style object to manufacture InstanceMetadataOptionsRequest.

Trait Implementations

impl Clone for InstanceMetadataOptionsRequest

fn clone(&self) -> InstanceMetadataOptionsRequest

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for InstanceMetadataOptionsRequest

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

Formats the value using the given formatter.

impl PartialEq<InstanceMetadataOptionsRequest> for InstanceMetadataOptionsRequest

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