Enum TransactionExpirationKind 

#[non_exhaustive]
#[repr(i32)]
pub enum TransactionExpirationKind {
    Unknown = 0,
    None = 1,
    Epoch = 2,
    ValidDuring = 3,
}

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.

Unknown = 0

None = 1

The transaction has no expiration.

Epoch = 2

Validators won’t sign and execute transaction unless the expiration epoch is greater than or equal to the current epoch.

ValidDuring = 3

This variant enables gas payments from address balances.

When transactions use address balances for gas payment instead of explicit gas coins, we lose the natural transaction uniqueness and replay prevention that comes from mutation of gas coin objects.

By bounding expiration and providing a nonce, validators must only retain executed digests for the maximum possible expiry range to differentiate retries from unique transactions with otherwise identical inputs.

Implementations

impl TransactionExpirationKind

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of TransactionExpirationKind.

pub fn from_i32(value: i32) -> Option<TransactionExpirationKind>

👎Deprecated: Use the TryFrom<i32> implementation instead

Converts an i32 to a TransactionExpirationKind, or None if value is not a valid variant.

impl TransactionExpirationKind

pub fn as_str_name(&self) -> &'static str

String value of the enum field names used in the ProtoBuf definition.

The values are not transformed in any way and thus are considered stable (if the ProtoBuf definition does not change) and safe for programmatic use.

pub fn from_str_name(value: &str) -> Option<Self>

Creates an enum from field names used in the ProtoBuf definition.

Trait Implementations

impl Clone for TransactionExpirationKind

fn clone(&self) -> TransactionExpirationKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TransactionExpirationKind

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

Formats the value using the given formatter.

impl Default for TransactionExpirationKind

fn default() -> TransactionExpirationKind

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TransactionExpirationKind

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<TransactionExpirationKind> for i32

fn from(value: TransactionExpirationKind) -> i32

Converts to this type from the input type.

impl Hash for TransactionExpirationKind

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

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 Ord for TransactionExpirationKind

fn cmp(&self, other: &TransactionExpirationKind) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for TransactionExpirationKind

fn eq(&self, other: &TransactionExpirationKind) -> 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 PartialOrd for TransactionExpirationKind

fn partial_cmp(&self, other: &TransactionExpirationKind) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for TransactionExpirationKind

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

where S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<i32> for TransactionExpirationKind

type Error = UnknownEnumValue

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<TransactionExpirationKind, UnknownEnumValue>

Performs the conversion.
