Enum aws_sdk_paymentcryptographydata::types::SessionKeyDerivationValue

#[non_exhaustive]
pub enum SessionKeyDerivationValue {
    ApplicationCryptogram(String),
    ApplicationTransactionCounter(String),
    Unknown,
}

Parameters to derive session key value using a MAC EMV algorithm.

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.

ApplicationCryptogram(String)

The cryptogram provided by the terminal during transaction processing.

ApplicationTransactionCounter(String)

The transaction counter that is provided by the terminal during transaction processing.

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 SessionKeyDerivationValue

pub fn as_application_cryptogram(&self) -> Result<&String, &Self>

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

pub fn is_application_cryptogram(&self) -> bool

Returns true if this is a ApplicationCryptogram.

pub fn as_application_transaction_counter(&self) -> Result<&String, &Self>

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

pub fn is_application_transaction_counter(&self) -> bool

Returns true if this is a ApplicationTransactionCounter.

pub fn is_unknown(&self) -> bool

Returns true if the enum instance is the Unknown variant.

Trait Implementations

impl Clone for SessionKeyDerivationValue

fn clone(&self) -> SessionKeyDerivationValue

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SessionKeyDerivationValue

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

Formats the value using the given formatter.

impl PartialEq for SessionKeyDerivationValue

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