Trait Implementations

impl AsRef<Header> for Header

fn as_ref(&self) -> &Header

Converts this type into a shared reference of the (usually inferred) input type.

impl BorshDeserialize for Header

fn deserialize_reader<__R: Read>(reader: &mut __R) -> Result<Self, Error>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for Header

fn serialize<__W: Write>(&self, writer: &mut __W) -> Result<(), Error>

impl Clone for Header

fn clone(&self) -> Header

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Header

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Header

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&GenesisBlock> for Header

fn from(genesis: &GenesisBlock) -> Self

Converts to this type from the input type.

impl From<Header> for DaaScoreTimestamp

fn from(header: Header) -> DaaScoreTimestamp

Converts to this type from the input type.

impl MemSizeEstimator for Header

fn estimate_mem_bytes(&self) -> usize

Estimates the (deep) size of this object in bytes (including heap owned inner data)

fn estimate_size(&self, mem_mode: MemMode) -> usize

Estimates the size of this object depending on the passed mem mode

fn estimate_mem_units(&self) -> usize

Estimates the number of units this object holds in memory where the unit byte size is usually a constant known to the caller as well (and hence we avoid computing it over and over)

impl Serialize for Header

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
