Struct cumulus_primitives_core::relay_chain::v2::CandidateHash

pub struct CandidateHash(pub H256);

Expand description

Unit type wrapper around Hash that represents a candidate hash.

This type is produced by CandidateReceipt::hash.

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

Tuple Fields§

§0: H256

Methods from Deref<Target = H256>§

pub fn as_bytes(&self) -> &[u8] ⓘ

Extracts a byte slice containing the entire fixed hash.

pub fn as_fixed_bytes(&self) -> &[u8; 32]

Extracts a reference to the byte array containing the entire fixed hash.

pub fn as_ptr(&self) -> *const u8

Returns a constant raw pointer to the value.

pub fn covers(&self, b: &H256) -> bool
