Enum aws_sdk_emr::types::Credentials

#[non_exhaustive]
pub enum Credentials {
    UsernamePassword(UsernamePassword),
    Unknown,
}

The credentials that you can use to connect to cluster endpoints. Credentials consist of a username and a password.

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.

UsernamePassword(UsernamePassword)

The username and password that you use to connect to cluster endpoints.

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 Credentials

pub fn as_username_password(&self) -> Result<&UsernamePassword, &Self>

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

pub fn is_username_password(&self) -> bool

Returns true if this is a UsernamePassword.

pub fn is_unknown(&self) -> bool

Returns true if the enum instance is the Unknown variant.

Trait Implementations

impl Clone for Credentials

fn clone(&self) -> Credentials

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Credentials

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

Formats the value using the given formatter.

impl PartialEq for Credentials

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