Enum TxKind

pub enum TxKind {
    Create,
    Call(Address),
}

The to field of a transaction. Either a target address, or empty for a contract creation.

Variants

Create

A transaction that creates a contract.

Call(Address)

A transaction that calls a contract or transfer.

Implementations

impl TxKind

pub const fn to(&self) -> Option<&Address>

Returns the address of the contract that will be called or will receive the transfer.

pub fn into_to(self) -> Option<Address>

Consumes the type and returns the address of the contract that will be called or will receive the transfer.

pub const fn is_create(&self) -> bool

Returns true if the transaction is a contract creation.

pub const fn is_call(&self) -> bool

Returns true if the transaction is a contract call.

pub const fn size(&self) -> usize

Calculates a heuristic for the in-memory size of this object.

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for TxKind

fn arbitrary(u: &mut Unstructured<'arbitrary>) -> Result<Self>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'arbitrary>) -> Result<Self>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

fn try_size_hint( depth: usize, ) -> Result<(usize, Option<usize>), MaxRecursionReached>

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

impl Arbitrary for TxKind

type Parameters = <Address as Arbitrary>::Parameters

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

type Strategy = TupleUnion<((u32, Arc<fn() -> TxKind>), (u32, Arc<Map<<Address as Arbitrary>::Strategy, fn(_: Address) -> TxKind>>))>

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

fn arbitrary_with(_top: Self::Parameters) -> Self::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 TxKind

fn clone(&self) -> TxKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TxKind

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

Formats the value using the given formatter.

impl Decodable for TxKind

Available on crate feature rlp only.

fn decode(buf: &mut &[u8]) -> Result<Self>

Decodes the blob into the appropriate type. buf must be advanced past the decoded object.

impl Default for TxKind

fn default() -> TxKind

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TxKind

Available on crate feature serde only.

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

Deserialize this value from the given Serde deserializer.

impl Encodable for TxKind

Available on crate feature rlp only.

fn encode(&self, out: &mut dyn BufMut)

Encodes the type into the out buffer.

fn length(&self) -> usize

Returns the length of the encoding of this type in bytes.

impl From<Address> for TxKind

fn from(value: Address) -> Self

Creates a TxKind::Call with the given address.

impl From<Option<Address>> for TxKind

fn from(value: Option<Address>) -> Self

Creates a TxKind::Call with the Some address, None otherwise.

impl From<TxKind> for Option<Address>

fn from(value: TxKind) -> Self

Returns the address of the contract that will be called or will receive the transfer.

impl Hash for TxKind

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 PartialEq for TxKind

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

Available on crate feature serde only.

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

Serialize this value into the given Serde serializer.

impl Copy for TxKind

impl Eq for TxKind

impl StructuralPartialEq for TxKind
