Struct HistoryEntryId 

pub struct HistoryEntryId(pub [u8; 16]);

Opaque: only ever compared for equality (revert/restore callbacks pass it back to the caller). The caller picks the byte layout — UUID-v4 today, a content hash later.

Tuple Fields

0: [u8; 16]

Implementations

impl HistoryEntryId

pub const fn from_bytes(bytes: [u8; 16]) -> HistoryEntryId

pub fn as_bytes(&self) -> &[u8; 16]

Trait Implementations

impl Clone for HistoryEntryId

fn clone(&self) -> HistoryEntryId

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HistoryEntryId

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

Formats the value using the given formatter.

impl Hash for HistoryEntryId

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for HistoryEntryId

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
