Trait Implementations

impl<N: Clone + Network> Clone for BatchHeader<N>

fn clone(&self) -> BatchHeader<N>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<N: Network> Debug for BatchHeader<N>

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

Prints the batch header as a JSON-string.

impl<'de, N: Network> Deserialize<'de> for BatchHeader<N>

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

Deserialize this value from the given Serde deserializer.

impl<N: Network> Display for BatchHeader<N>

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

Displays the batch header as a JSON-string.

impl<N: Network> FromBytes for BatchHeader<N>

fn read_le<R: Read>(reader: R) -> IoResult<Self>

Reads the batch header from the buffer.

fn from_bytes_le(bytes: &[u8]) -> Result<Self, Error>where Self: Sized,

Returns Self from a byte array in little-endian order.

impl<N: Network> FromStr for BatchHeader<N>

fn from_str(header: &str) -> Result<Self, Self::Err>

Initializes the batch header from a JSON-string.

type Err = Error

The associated error which can be returned from parsing.

impl<N: PartialEq + Network> PartialEq for BatchHeader<N>

fn eq(&self, other: &BatchHeader<N>) -> bool

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

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<N: Network> Serialize for BatchHeader<N>

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

Serialize this value into the given Serde serializer.

impl<N: Network> ToBytes for BatchHeader<N>

fn write_le<W: Write>(&self, writer: W) -> IoResult<()>

Writes the batch header to the buffer.

fn to_bytes_le(&self) -> Result<Vec<u8>, Error>where Self: Sized,

Returns self as a byte array in little-endian order.
