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.

instance_id: Option<String>

The ID of the instance.

http_tokens: Option<HttpTokensState>

Indicates whether IMDSv2 is required.

• optional - IMDSv2 is optional. You can choose whether to send a session token in your instance metadata retrieval requests. If you retrieve IAM role credentials without a session token, you receive the IMDSv1 role credentials. If you retrieve IAM role credentials using a valid session token, you receive the IMDSv2 role credentials.

• required - IMDSv2 is required. You must send a session token in your instance metadata retrieval requests. With this option, retrieving the IAM role credentials always returns IMDSv2 credentials; IMDSv1 credentials are not available.

Default:

• If the value of ImdsSupport for the Amazon Machine Image (AMI) for your instance is v2.0 and the account level default is set to no-preference, the default is required.

• If the value of ImdsSupport for the Amazon Machine Image (AMI) for your instance is v2.0, but the account level default is set to V1 or V2, the default is optional.

The default value can also be affected by other combinations of parameters. For more information, see Order of precedence for instance metadata options in the Amazon EC2 User Guide.

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. If no parameter is specified, the existing state is maintained.

Possible values: Integers from 1 to 64

http_endpoint: Option<InstanceMetadataEndpointState>

Enables or disables the HTTP metadata endpoint on your instances. If this parameter is not specified, the existing state is maintained.

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

dry_run: Option<bool>

Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

http_protocol_ipv6: Option<InstanceMetadataProtocolState>

Enables or disables the IPv6 endpoint for the instance metadata service. Applies only if you enabled the HTTP metadata endpoint.

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.

impl ModifyInstanceMetadataOptionsInput

pub fn builder() -> ModifyInstanceMetadataOptionsInputBuilder

Creates a new builder-style object to manufacture ModifyInstanceMetadataOptionsInput.

Trait Implementations

impl Clone for ModifyInstanceMetadataOptionsInput

fn clone(&self) -> ModifyInstanceMetadataOptionsInput

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ModifyInstanceMetadataOptionsInput

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

Formats the value using the given formatter.

impl PartialEq for ModifyInstanceMetadataOptionsInput

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