Struct VersionStamp

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

Versionstamp is a 10-byte array used to identify a specific version of a key. The first 8 bytes are significant (the u64), and the remaining 2 bytes are not significant, but used for extra precision. To convert to and from this module, see the conv module in this same directory.

Implementations

impl VersionStamp

pub const ZERO: VersionStamp

pub const fn from_u64(v: u64) -> Self

pub const fn from_u64_u16(v: u64, v2: u16) -> Self

pub const fn try_from_u128(v: u128) -> Result<Self, VersionStampError>

pub const fn into_u64_u16(self) -> (u64, u16)

Convert the VersionStamp into a u64 ignoring the 2 normally zero bytes.

pub const fn into_u64_lossy(self) -> u64

Convert the VersionStamp into a u64 ignoring the 2 normally zero bytes.

pub const fn try_into_u64(self) -> Result<u64, VersionStampError>

pub const fn into_u128(self) -> u128

pub const fn as_bytes(self) -> [u8; 10]

pub const fn from_bytes(bytes: [u8; 10]) -> Self

pub const fn from_slice(slice: &[u8]) -> Result<Self, VersionStampError>

pub fn next(self) -> Option<Self>

pub fn iter(self) -> VersionStampIter

Returns an iterator of version stamps starting with the current version stamp.

Trait Implementations

impl Clone for VersionStamp

fn clone(&self) -> VersionStamp

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VersionStamp

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

Formats the value using the given formatter.

impl Default for VersionStamp

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for VersionStamp

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for VersionStamp

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,

Feeds a slice of this type into the given Hasher.

impl PartialEq for VersionStamp

fn eq(&self, other: &VersionStamp) -> 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.

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Revisioned for VersionStamp

fn revision() -> u16

Returns the current revision of this type.

fn serialize_revisioned<W: Write>(&self, w: &mut W) -> Result<(), Error>

Serializes the struct using the specficifed writer.

fn deserialize_revisioned<R: Read>(r: &mut R) -> Result<Self, Error>

where Self: Sized,

Deserializes a new instance of the struct from the specficifed reader.

fn type_id() -> TypeId

where Self: 'static,

Returns the type id of this type.
