Performs the + operation. Read more

impl AddAssign<u64> for ForkHash

fn add_assign(&mut self, block: BlockNumber)

Performs the += operation. Read more

impl Clone for ForkHash

fn decode(rlp: &Rlp<'_>) -> Result<Self, DecoderError>

Decode a value from RLP bytes

impl Encodable for ForkHash

fn rlp_append(&self, s: &mut RlpStream)

Append a value to the stream

fn rlp_bytes(&self) -> Vec<u8, Global>

impl MallocSizeOf for ForkHash

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself. If T::size_of is a constant, consider implementing constant_size as well. Read more

fn constant_size() -> Option<usize>

Used to optimize MallocSizeOf implementation for collections like Vec and HashMap to avoid iterating over them unnecessarily. The Self: Sized bound is for object safety. Read more

fn eq(&self, other: &ForkHash) -> bool

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

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

This method tests for !=.
