Struct ContentionKey 

pub struct ContentionKey {
    pub utxo_id: Option<UtxoId>,
    pub address: Option<Address>,
    pub selector: Option<StateSelector>,
    pub transaction_hash: Option<Hash>,
}

Any value which can cause a conflict or collision among nodes due to disagreements in ordering.

Fields

utxo_id: Option<UtxoId>

Classical conflict condition associated with double spends, two transactions which share a common parent causing a conflict or contention.

address: Option<Address>

Conflict conditions associated with deployed single-address contracts

selector: Option<StateSelector>

Combined with above address – imposes a conflict ordering condition among a state subset denoted by a key index

transaction_hash: Option<Hash>

Duplicate transaction hash conflict condition – associated with duplicate processing of same data. Primarily used internally for tracking internal contentions.

Implementations

impl ContentionKey

pub fn contract_request( address: &Address, selector: Option<&StateSelector>, ) -> ContentionKey

Trait Implementations

impl Clone for ContentionKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContentionKey

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

Formats the value using the given formatter.

impl Default for ContentionKey

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ContentionKey

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for ContentionKey

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 HashClear for ContentionKey

fn hash_clear(&mut self)

impl Message for ContentionKey

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message to a buffer.

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

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message with a length-delimiter to a buffer.

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

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for ContentionKey

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
