Struct BlockHash 

pub struct BlockHash;

Get the hash of one of the 256 most recent complete blocks.

Trait Implementations

impl Clone for BlockHash

fn clone(&self) -> BlockHash

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlockHash

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

Formats the value using the given formatter.

impl Display for BlockHash

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

Formats the value using the given formatter.

impl Hash for BlockHash

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Instruction for BlockHash

fn opcode(&self) -> OpCode

Return the operation code associated with this instruction.

fn is_push(&self) -> bool

Returns a value signifying whether this instruction is of the type PUSHx.

fn is_dup(&self) -> bool

Returns a value signifying whether this instruction is of the type DUPx.

fn is_swap(&self) -> bool

Returns a value signifying whether this instruction is of the type SWAPx.

fn is_log(&self) -> bool

Returns a value signifying whether this instruction is of the type LOGx.

fn is_terminator(&self) -> bool

Returns true for instructions that terminate execution of the smart contract.

impl PartialEq for BlockHash

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

Tests for self and other values to be equal, and is used by ==.

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

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