Struct InstanceMetadataOptions 

#[non_exhaustive]
pub struct InstanceMetadataOptions {
    pub http_tokens: Option<InstanceMetadataHttpTokensState>,
    pub http_put_response_hop_limit: Option<i32>,
    pub http_endpoint: Option<InstanceMetadataEndpointState>,
}

The metadata options for the instances. For more information, see Configure the instance metadata options in the Amazon EC2 Auto Scaling User 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.

http_tokens: Option<InstanceMetadataHttpTokensState>

The state of token usage for your instance metadata requests. If the parameter is not specified in the request, the default state is optional.

If the state is optional, you can choose to retrieve instance metadata with or without a signed token header on your request. If you retrieve the IAM role credentials without a token, the version 1.0 role credentials are returned. If you retrieve the IAM role credentials using a valid signed token, the version 2.0 role credentials are returned.

If the state is required, you must send a signed token header with any instance metadata retrieval requests. In this state, retrieving the IAM role credentials always returns the version 2.0 credentials; the version 1.0 credentials are not available.

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

http_endpoint: Option<InstanceMetadataEndpointState>

This parameter enables or disables the HTTP metadata endpoint on your instances. If the parameter is not specified, the default state is enabled.

If you specify a value of disabled, you will not be able to access your instance metadata.

Implementations

impl InstanceMetadataOptions

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

The state of token usage for your instance metadata requests. If the parameter is not specified in the request, the default state is optional.

If the state is optional, you can choose to retrieve instance metadata with or without a signed token header on your request. If you retrieve the IAM role credentials without a token, the version 1.0 role credentials are returned. If you retrieve the IAM role credentials using a valid signed token, the version 2.0 role credentials are returned.

If the state is required, you must send a signed token header with any instance metadata retrieval requests. In this state, retrieving the IAM role credentials always returns the version 2.0 credentials; the version 1.0 credentials are not available.

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

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

This parameter enables or disables the HTTP metadata endpoint on your instances. If the parameter is not specified, the default state is enabled.

If you specify a value of disabled, you will not be able to access your instance metadata.

impl InstanceMetadataOptions

pub fn builder() -> InstanceMetadataOptionsBuilder

Creates a new builder-style object to manufacture InstanceMetadataOptions.

Trait Implementations

impl Clone for InstanceMetadataOptions

fn clone(&self) -> InstanceMetadataOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InstanceMetadataOptions

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

Formats the value using the given formatter.

impl PartialEq for InstanceMetadataOptions

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