Struct TxContext 

pub struct TxContext {
    pub sender: Address,
    pub tx_hash: MoveVec<u8>,
    pub epoch: u64,
    pub epoch_timestamp_ms: u64,
    pub ids_created: u64,
}

Information about the transaction currently being executed. This cannot be constructed by a transaction–it is a privileged object created by the VM and passed in to the entrypoint of the transaction as &mut TxContext.

Fields

sender: Address

The address of the user that signed the current transaction

tx_hash: MoveVec<u8>

Hash of the current transaction

epoch: u64

The current epoch number

epoch_timestamp_ms: u64

Timestamp that the epoch started at

ids_created: u64

Counter recording the number of fresh id’s created while executing this transaction. Always 0 at the start of a transaction

Implementations

impl TxContext

pub fn new( sender: Address, tx_hash: MoveVec<u8>, epoch: u64, epoch_timestamp_ms: u64, ids_created: u64, ) -> Self

Constructs a new TxContext.

impl TxContext

pub fn move_instance(self) -> MoveInstance<Self>

pub fn type_() -> TxContextTypeTag

Trait Implementations

impl Clone for TxContext

fn clone(&self) -> TxContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TxContext

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TxContext

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for TxContext

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

Formats the value using the given formatter.

impl Hash for TxContext

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 MoveStruct for TxContext

type StructTag = TxContextTypeTag

impl MoveType for TxContext

type TypeTag = TxContextTypeTag

fn from_bcs(bytes: &[u8]) -> Result<Self, Error>

Deserialize the contents of the Move type from BCS bytes.

fn into_bcs(self) -> Result<Vec<u8>, Error>

Consuming version of to_bcs.

fn to_bcs(&self) -> Result<Vec<u8>, Error>

Serialize the contents of the Move type to BCS bytes.

fn into_json(self) -> Value

Consuming version of to_json.

fn to_json(&self) -> Value

Serialize the contents of the Move type to JSON.

impl PartialEq for TxContext

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

fn module() -> Identifier

impl StaticName for TxContext

fn name() -> Identifier

impl StaticTypeParams for TxContext

fn type_params() -> Vec<TypeTag>

impl Tabled for TxContext

const LENGTH: usize = 5usize

A length of fields and headers, which must be the same.

fn fields(&self) -> Vec<Cow<'_, str>>

Fields method must return a list of cells.

fn headers() -> Vec<Cow<'static, str>>

Headers must return a list of column names.
