Enum AuthenticationMetadata 

#[non_exhaustive]
pub enum AuthenticationMetadata {
    ApiKeyConnectionMetadata(ApiKeyConnectionMetadata),
    AuthorizationCodeGrantMetadata(AuthorizationCodeGrantMetadata),
    BasicAuthConnectionMetadata(BasicAuthConnectionMetadata),
    ClientCredentialsGrantMetadata(ClientCredentialsGrantMetadata),
    IamConnectionMetadata(IamConnectionMetadata),
    NoneConnectionMetadata(NoneConnectionMetadata),
    #[non_exhaustive]
    Unknown,
}

Union type containing authentication metadata for different authentication methods.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ApiKeyConnectionMetadata(ApiKeyConnectionMetadata)

API key authentication metadata.

AuthorizationCodeGrantMetadata(AuthorizationCodeGrantMetadata)

OAuth 2.0 authorization code grant authentication metadata.

BasicAuthConnectionMetadata(BasicAuthConnectionMetadata)

Basic authentication metadata using username and password.

ClientCredentialsGrantMetadata(ClientCredentialsGrantMetadata)

OAuth 2.0 client credentials grant authentication metadata.

IamConnectionMetadata(IamConnectionMetadata)

IAM role-based authentication metadata for Amazon Web Services services.

NoneConnectionMetadata(NoneConnectionMetadata)

No authentication metadata for services that don't require authentication.

#[non_exhaustive]

Unknown

The Unknown variant represents cases where new union variant was received. Consider upgrading the SDK to the latest available version. An unknown enum variant

Note: If you encounter this error, consider upgrading your SDK to the latest version. The Unknown variant represents cases where the server sent a value that wasn’t recognized by the client. This can happen when the server adds new functionality, but the client has not been updated. To investigate this, consider turning on debug logging to print the raw HTTP response.

Implementations

impl AuthenticationMetadata

pub fn as_api_key_connection_metadata( &self, ) -> Result<&ApiKeyConnectionMetadata, &Self>

Tries to convert the enum instance into ApiKeyConnectionMetadata, extracting the inner ApiKeyConnectionMetadata. Returns Err(&Self) if it can’t be converted.

pub fn is_api_key_connection_metadata(&self) -> bool

Returns true if this is a ApiKeyConnectionMetadata.

pub fn as_authorization_code_grant_metadata( &self, ) -> Result<&AuthorizationCodeGrantMetadata, &Self>

Tries to convert the enum instance into AuthorizationCodeGrantMetadata, extracting the inner AuthorizationCodeGrantMetadata. Returns Err(&Self) if it can’t be converted.

pub fn is_authorization_code_grant_metadata(&self) -> bool

Returns true if this is a AuthorizationCodeGrantMetadata.

pub fn as_basic_auth_connection_metadata( &self, ) -> Result<&BasicAuthConnectionMetadata, &Self>

Tries to convert the enum instance into BasicAuthConnectionMetadata, extracting the inner BasicAuthConnectionMetadata. Returns Err(&Self) if it can’t be converted.

pub fn is_basic_auth_connection_metadata(&self) -> bool

Returns true if this is a BasicAuthConnectionMetadata.

pub fn as_client_credentials_grant_metadata( &self, ) -> Result<&ClientCredentialsGrantMetadata, &Self>

Tries to convert the enum instance into ClientCredentialsGrantMetadata, extracting the inner ClientCredentialsGrantMetadata. Returns Err(&Self) if it can’t be converted.

pub fn is_client_credentials_grant_metadata(&self) -> bool

Returns true if this is a ClientCredentialsGrantMetadata.

pub fn as_iam_connection_metadata( &self, ) -> Result<&IamConnectionMetadata, &Self>

Tries to convert the enum instance into IamConnectionMetadata, extracting the inner IamConnectionMetadata. Returns Err(&Self) if it can’t be converted.

pub fn is_iam_connection_metadata(&self) -> bool

Returns true if this is a IamConnectionMetadata.

pub fn as_none_connection_metadata( &self, ) -> Result<&NoneConnectionMetadata, &Self>

Tries to convert the enum instance into NoneConnectionMetadata, extracting the inner NoneConnectionMetadata. Returns Err(&Self) if it can’t be converted.

pub fn is_none_connection_metadata(&self) -> bool

Returns true if this is a NoneConnectionMetadata.

pub fn is_unknown(&self) -> bool

Returns true if the enum instance is the Unknown variant.

Trait Implementations

impl Clone for AuthenticationMetadata

fn clone(&self) -> AuthenticationMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AuthenticationMetadata

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

Formats the value using the given formatter.

impl PartialEq for AuthenticationMetadata

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