Struct exonum::blockchain::TxLocation

pub struct TxLocation { /* fields omitted */ }

Transaction location in block.

Methods

impl TxLocation

fn new(block_height: Height, position_in_block: u64) -> TxLocation

Creates a new instance with given parameters.

fn hash(&self) -> Hash

Hashes data as a raw byte array and returns the resulting hash.

fn block_height(&self) -> Height

Height of block in the blockchain.

fn position_in_block(&self) -> u64

Index in block.

Trait Implementations

impl Clone for TxLocation

fn clone(&self) -> TxLocation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq for TxLocation

fn eq(&self, __arg_0: &TxLocation) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &TxLocation) -> bool

This method tests for !=.

impl<'a> Field<'a> for TxLocation

unsafe fn read(buffer: &'a [u8], from: Offset, to: Offset) -> Self

Read Field from buffer, with given position, beware of memory unsafety, you should check Field before read.

fn write(&self, buffer: &mut Vec<u8>, from: Offset, to: Offset)

Write Field to buffer, in given position write doesn't lead to memory unsafety.

fn check(
    buffer: &'a [u8],
    from_st_val: CheckedOffset,
    to_st_val: CheckedOffset,
    latest_segment: CheckedOffset
) -> Result

Checks if data in the buffer could be deserialized. Returns an index of latest data seen.

fn field_size() -> Offset

Field's header size

impl StorageValue for TxLocation

fn into_bytes(self) -> Vec<u8>

Serialize a value into a vector of bytes.

fn from_bytes(v: Cow<[u8]>) -> Self

Deserialize a value from bytes.

fn hash(&self) -> Hash

Returns a hash of the value.

impl Debug for TxLocation

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

Formats the value using the given formatter.

impl ExonumJson for TxLocation

fn deserialize_field<B>(
    value: &Value,
    buffer: &mut B,
    from: Offset,
    to: Offset
) -> Result<(), Box<Error>> where
    B: WriteBufferWrapper, 

write deserialized field in buffer on place.

fn serialize_field(&self) -> Result<Value, Box<Error>>

serialize field as json::Value

impl ExonumJsonDeserialize for TxLocation

fn deserialize(value: &Value) -> Result<Self, Box<Error>>

deserialize json value.

impl<'de> Deserialize<'de> for TxLocation

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

Deserialize this value from the given Serde deserializer.

impl Serialize for TxLocation

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

Serialize this value into the given Serde serializer.
