Struct polkadot_core_primitives::CandidateHash
source · pub struct CandidateHash(pub Hash);
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.

§0: Hash
Methods from Deref<Target = Hash>§
sourcepub fn as_fixed_bytes(&self) -> &[u8; 32]
pub fn as_fixed_bytes(&self) -> &[u8; 32]
Extracts a reference to the byte array containing the entire fixed hash.
sourcepub fn to_low_u64_be(&self) -> u64
pub fn to_low_u64_be(&self) -> u64
Returns the lowest 8 bytes interpreted as big-endian.
§Note
For hash type with less than 8 bytes the missing bytes are interpreted as being zero.
sourcepub fn to_low_u64_le(&self) -> u64
pub fn to_low_u64_le(&self) -> u64
Returns the lowest 8 bytes interpreted as little-endian.
§Note
For hash type with less than 8 bytes the missing bytes are interpreted as being zero.
sourcepub fn to_low_u64_ne(&self) -> u64
pub fn to_low_u64_ne(&self) -> u64
Returns the lowest 8 bytes interpreted as native-endian.
§Note
For hash type with less than 8 bytes the missing bytes are interpreted as being zero.
