Struct polkadot_parachain_primitives::primitives::ValidationCodeHash

pub struct ValidationCodeHash(/* private fields */);

Unit type wrapper around Hash that represents the blake2-256 hash of validation code in particular.

This type is produced by ValidationCode::hash.

This type makes it easy to enforce that a hash is a validation code hash on the type level.

Trait Implementations

impl Display for ValidationCodeHash

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

Formats the value using the given formatter.

impl Encode for ValidationCodeHash

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8>

Convert self to an owned vector.

fn using_encoded<__CodecOutputReturn, __CodecUsingEncodedCallback: FnOnce(&[u8]) -> __CodecOutputReturn>( &self, f: __CodecUsingEncodedCallback, ) -> __CodecOutputReturn

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl From<[u8; 32]> for ValidationCodeHash

fn from(hash: [u8; 32]) -> ValidationCodeHash

Converts to this type from the input type.

impl From<H256> for ValidationCodeHash

fn from(hash: Hash) -> ValidationCodeHash

Converts to this type from the input type.

impl Hash for ValidationCodeHash

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,

impl LowerHex for ValidationCodeHash

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

Formats the value using the given formatter.

impl Ord for ValidationCodeHash

fn cmp(&self, other: &ValidationCodeHash) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for ValidationCodeHash

fn eq(&self, other: &ValidationCodeHash) -> 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 PartialOrd for ValidationCodeHash

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

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

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

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

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

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

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

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

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