Struct ChainOutput 

pub struct ChainOutput<T> {
    tx_hash: HashBase<CoreWrapper<Keccak256Core>>,
    output: Option<T>,
}

Represents an output of a write operation to the chain performed by the node.

This consists always of a transaction hash and an optional output T.

Operations that produce no useful output use () as T.

Fields

tx_hash: HashBase<CoreWrapper<Keccak256Core>>

output: Option<T>

Implementations

impl<T> ChainOutput<T>

pub fn new( tx_hash: HashBase<CoreWrapper<Keccak256Core>>, output: T, ) -> ChainOutput<T>

Creates a new ChainOutput with the given transaction hash and output.

pub fn tx_hash(&self) -> &HashBase<CoreWrapper<Keccak256Core>>

Returns the transaction hash of the chain operation.

pub fn output(&self) -> Option<&T>

Returns the optional output of the chain operation.

impl ChainOutput<()>

pub fn new_empty( tx_hash: HashBase<CoreWrapper<Keccak256Core>>, ) -> ChainOutput<()>

Creates a new ChainOutput with the given transaction hash and no output.

Trait Implementations

impl<T> Clone for ChainOutput<T>

where T: Clone,

fn clone(&self) -> ChainOutput<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Debug for ChainOutput<T>

where T: Debug,

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

Formats the value using the given formatter.

impl<T> Default for ChainOutput<T>

where T: Default,

fn default() -> ChainOutput<T>

Returns the “default value” for a type.

impl<'de, T> Deserialize<'de> for ChainOutput<T>

where T: Deserialize<'de>,

fn deserialize<__D>( __deserializer: __D, ) -> Result<ChainOutput<T>, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<HashBase<CoreWrapper<Keccak256Core>>> for ChainOutput<()>

fn from(tx_hash: HashBase<CoreWrapper<Keccak256Core>>) -> ChainOutput<()>

Converts to this type from the input type.

impl<T> Hash for ChainOutput<T>

where T: Hash,

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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<T> PartialEq for ChainOutput<T>

where T: PartialEq,

fn eq(&self, other: &ChainOutput<T>) -> 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.
