size of item fixed part that this Field collect.

fn count(&self) -> Offset

count of items in collection

fn extend_buffer(&self, buffer: &mut Vec<u8>)

extend buffer with this collection

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

create collection from buffer

fn check_data(
    buffer: &'a [u8],
    from: CheckedOffset,
    count: CheckedOffset,
    latest_segment: CheckedOffset
) -> Result

check collection data

impl AsRef<RawMessage> for MsgAnchoringSignature

fn as_ref(&self) -> &RawMessage

Performs the conversion.

impl FromHex for MsgAnchoringSignature

type Error = Error

fn from_hex<T: AsRef<[u8]>>(hex: T) -> Result<Self, Self::Error>

Creates an instance of type Self from the given hex string, or fails with a custom error type.

impl StorageValue for MsgAnchoringSignature

Important traits for Vec<u8>

impl Write for Vec<u8>

fn into_bytes(self) -> Vec<u8>

Serialize a value into a vector of bytes.

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

Deserialize a value from bytes.

impl Debug for MsgAnchoringSignature

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

Formats the value using the given formatter.

impl ExonumJson for MsgAnchoringSignature

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 + Send + Sync>>

serialize field as json::Value

impl ExonumJsonDeserialize for MsgAnchoringSignature

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

impl Transaction for MsgAnchoringSignature

fn verify(&self) -> bool

Verifies the internal consistency of the transaction. verify should usually include checking the message signature (via [verify_signature]) and, possibly, other internal constraints. verify has no access to the blockchain state; checks involving the blockchains state must be preformed in execute.

fn execute(&self, fork: &mut Fork) -> ExecutionResult

Receives a fork of the current blockchain state and can modify it depending on the contents of the transaction.
