Fields

sender: AccountId

Transaction sender

Maximum gas to spend

gas_price: GasPrice

Gas price per unit

kind: TransactionKind

Transaction kind and parameters

signature: Signature

Digital signature

Implementations

impl Transaction

pub fn new( sender: AccountId, nonce: Nonce, gas_limit: Gas, gas_price: GasPrice, kind: TransactionKind, signature: Signature, ) -> Self

Create a new transaction

pub fn hash(&self) -> Hash

Get transaction hash

pub fn fee(&self) -> Balance

Get transaction fee (gas_limit * gas_price)

pub fn verify_signature(&self) -> PrimitiveResult<bool>

Check if transaction is signed by the claimed sender

pub fn signature_message(&self) -> Vec<u8>

Get the message that should be signed

pub fn is_system_transaction(&self) -> bool

Check if transaction is a system transaction (no fee required)

pub fn weight(&self) -> Weight

Get the transaction weight (for block weight calculations)

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 Decode for Transaction

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy, ) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self>, ) -> Result<DecodeFinished, Error>

where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>

where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

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 Encode for Transaction

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy, )

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> R

where F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl EncodeLike for Transaction

impl Eq for Transaction

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 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 StructuralPartialEq for Transaction

impl Validate for Transaction

fn validate(&self) -> PrimitiveResult<()>
