Struct Transaction 

pub struct Transaction { /* private fields */ }

An transaction is a unique, universal and efficient identifier for any roundtrip transaction as it is broadcasted around the Freenet network.

The identifier conveys all necessary information to identify and classify the transaction:

• The unique identifier itself.
• The type of transaction being performed.
• If the transaction has been finalized, this allows for the connection manager to sweep any garbage left by a finished (or timed out) transaction.

A transaction may span different messages sent across the network.

Implementations

impl Transaction

pub const NULL: &'static Transaction

pub fn parent_id(&self) -> Option<&Ulid>

Returns the parent transaction ID for child operations.

pub fn is_sub_operation(&self) -> bool

Returns true if this transaction is a child operation.

pub fn timed_out(&self) -> bool

pub fn id_bytes(&self) -> [u8; 16]

Returns the transaction ID as raw bytes. Used for deriving hash keys in bloom filters.

pub fn elapsed(&self) -> Duration

Returns the elapsed time since this transaction was created.

pub fn ttl_transaction() -> Self

Generate a random transaction which has the implicit TTL cutoff.

This will allow, for example, to compare against any older transactions, in order to remove them.

Trait Implementations

impl Clone for Transaction

fn clone(&self) -> Transaction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Transaction

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Transaction

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Transaction

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

Formats the value using the given formatter.

impl Hash for Transaction

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 Transaction

fn cmp(&self, other: &Self) -> 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 Transaction

fn eq(&self, other: &Transaction) -> 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 Transaction

fn partial_cmp(&self, other: &Self) -> 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 Transaction

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Transaction

impl Eq for Transaction
