Struct Transaction

pub struct Transaction {
    pub version: Version,
    pub cell_deps: Vec<CellDep>,
    pub header_deps: Vec<H256>,
    pub inputs: Vec<CellInput>,
    pub outputs: Vec<CellOutput>,
    pub outputs_data: Vec<JsonBytes>,
    pub witnesses: Vec<JsonBytes>,
}

The transaction.

Refer to RFC CKB Transaction Structure.

Fields

version: Version

Reserved for future usage. It must equal 0 in current version.

cell_deps: Vec<CellDep>

An array of cell deps.

CKB locates lock script and type script code via cell deps. The script also can use syscalls to read the cells here.

Unlike inputs, the live cells can be used as cell deps in multiple transactions.

header_deps: Vec<H256>

An array of header deps.

The block must already be in the canonical chain.

Lock script and type script can read the header information of blocks listed here.

inputs: Vec<CellInput>

An array of input cells.

In the canonical chain, any cell can only appear as an input once.

outputs: Vec<CellOutput>

An array of output cells.

outputs_data: Vec<JsonBytes>

Output cells data.

This is a parallel array of outputs. The cell capacity, lock, and type of the output i is outputs[i] and its data is outputs_data[i].

witnesses: Vec<JsonBytes>

An array of variable-length binaries.

Lock script and type script can read data here to verify the transaction.

For example, the bundled secp256k1 lock script requires storing the signature in witnesses.

Trait Implementations

impl Clone for Transaction

fn clone(&self) -> Transaction

Returns a copy 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 Default for Transaction

fn default() -> Transaction

Returns the “default value” for a 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 From<Transaction> for Transaction

fn from(input: Transaction) -> Self

Converts to this type from the input type.

impl From<Transaction> for Transaction

fn from(json: Transaction) -> Self

Converts to this type from the input type.

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 JsonSchema for Transaction

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(gen: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

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 Eq for Transaction

impl StructuralPartialEq for Transaction
