Trait Implementations

impl Eq for H256

impl PartialEq<H256> for H256

fn eq(&self, other: &H256) -> bool

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

#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl Debug for H256

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

Formats the value using the given formatter.

impl FromStr for H256

type Err = FromHexError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<H256, <H256 as FromStr>::Err>

Parses a string s to return a value of this type.

impl Deref for H256

type Target = [u8; 32]

The resulting type after dereferencing.

fn deref(&self) -> &<H256 as Deref>::Target

Dereferences the value.

impl AsRef<H256> for H256

fn as_ref(&self) -> &H256

Performs the conversion.

impl Hash for H256

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

Feeds this value into the given [Hasher].

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

Feeds a slice of this type into the given [Hasher].

impl From<&'static str> for H256

fn from(s: &'static str) -> H256

Performs the conversion.

impl From<H256> for [u8; 32]

fn from(h: H256) -> [u8; 32]

Performs the conversion.

impl<'a> From<&'a [u8]> for H256

fn from(slc: &[u8]) -> H256

Performs the conversion.

impl From<[u8; 32]> for H256

fn from(h: [u8; 32]) -> H256

Performs the conversion.

impl From<u8> for H256

fn from(v: u8) -> H256

Performs the conversion.

impl PartialOrd<H256> for H256

fn partial_cmp(&self, other: &H256) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use] fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use] fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use] fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use] fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl HeapSizeOf for H256

fn heap_size_of_children(&self) -> usize

Measure the size of any heap-allocated structures that hang off this value, but not the space taken up by the value itself (i.e. what size_of:: measures, more or less); that space is handled by the implementation of HeapSizeOf for Box below.

impl Display for H256

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

Formats the value using the given formatter.

impl Clone for H256

fn clone(&self) -> H256

Returns a copy of the value.
