Struct TransactionHeader

    pub last_valid: u64,
    pub genesis_hash: Option<Byte32>,

}

Common header fields shared by all transaction types.

This structure contains the fields that are present in every transaction, regardless of transaction type.

Fields

sender: Address

The account that authorized the transaction.

Fees are deducted from this account.

fee: Option<u64>

Optional transaction fee in microALGO.

When None, the fee will be interpreted as 0 by the network.

first_valid: u64

First round for when the transaction is valid.

last_valid: u64

Last round for when the transaction is valid.

After this round, the transaction will be expired.

genesis_hash: Option<Byte32>

Hash of the genesis block of the network.

Used to identify which network the transaction is for.

genesis_id: Option<String>

Genesis ID of the network.

A human-readable string used alongside genesis hash to identify the network.

note: Option<Vec<u8>>

Optional user-defined note field.

Can contain arbitrary data up to 1KB in size.

rekey_to: Option<Address>

Optional authorized account for future transactions.

If set, only this account will be used for transaction authorization going forward. Reverting back control to the original address must be done by setting this field to the original address.

lease: Option<Byte32>

Optional lease value to enforce mutual transaction exclusion.

When a transaction with a non-empty lease field is confirmed, the lease is acquired. A lease X is acquired by the sender, generating the (sender, X) lease. The lease is kept active until the last_valid round of the transaction has elapsed. No other transaction sent by the same sender can be confirmed until the lease expires.

group: Option<Byte32>

Optional group ID for atomic transaction grouping.

Transactions with the same group ID must execute together or not at all.

Trait Implementations

impl Clone for TransactionHeader

fn clone(&self) -> TransactionHeader

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TransactionHeader

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TransactionHeader

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TransactionHeader

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
