Enum TransactionExpiration 

#[non_exhaustive]
pub enum TransactionExpiration {
    None,
    Epoch(u64),
}

A TTL for a transaction

BCS

The BCS serialized form for this type is defined by the following ABNF:

transaction-expiration =  %d00      ; none
                       =/ %d01 u64  ; epoch

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.

None

The transaction has no expiration

Epoch(u64)

Validators won’t sign a transaction unless the expiration Epoch is greater than or equal to the current epoch

Implementations

impl TransactionExpiration

pub fn is_none(&self) -> bool

Checks if this is a none variant.

pub fn is_epoch(&self) -> bool

Checks if this is a epoch variant.

pub fn as_epoch(&self) -> &u64

Converts this into a epoch if it is a epoch variant, or panics otherwise.

pub fn as_epoch_mut(&mut self) -> &mut u64

Converts this into a mut epoch if it is a epoch variant, or panics otherwise.

pub fn as_epoch_opt(&self) -> Option<&u64>

Converts this into a epoch if it is a epoch variant, or returns None otherwise.

pub fn as_epoch_mut_opt(&mut self) -> Option<&mut u64>

Converts this into a mut epoch if it is a epoch variant, or returns None otherwise.

pub fn into_epoch_opt(self) -> Option<u64>

Converts this into a epoch if it is a epoch variant, or returns None otherwise.

pub fn into_epoch(self) -> u64

Converts this into a epoch if it is a epoch variant, or panics otherwise.

Trait Implementations

impl Arbitrary for TransactionExpiration

type Parameters = ()

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = BoxedStrategy<TransactionExpiration>

The type of Strategy used to generate values of type Self.

fn arbitrary_with( args_shared: <TransactionExpiration as Arbitrary>::Parameters, ) -> <TransactionExpiration as Arbitrary>::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl Clone for TransactionExpiration

fn clone(&self) -> TransactionExpiration

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TransactionExpiration

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

Formats the value using the given formatter.

impl Default for TransactionExpiration

fn default() -> TransactionExpiration

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TransactionExpiration

fn deserialize<D>( deserializer: D, ) -> Result<TransactionExpiration, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for TransactionExpiration

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TransactionExpiration

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

impl Serialize for TransactionExpiration

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
