Struct polkadot_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.

fn using_encoded<__CodecOutputReturn, __CodecUsingEncodedCallback>( &self, f: __CodecUsingEncodedCallback, ) -> __CodecOutputReturn

where __CodecUsingEncodedCallback: FnOnce(&[u8]) -> __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: H256) -> ValidationCodeHash

Converts to this type from the input type.

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,

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

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.
