Struct TxId 

#[repr(transparent)]
pub struct TxId(pub u64);

Unique identifier for a transaction.

Transaction IDs are monotonically increasing and used for MVCC versioning.

Tuple Fields

0: u64

Implementations

impl TxId

pub const INVALID: Self

The invalid/null transaction ID.

pub const fn new(id: u64) -> Self

Creates a new TxId from a raw u64 value.

pub const fn as_u64(self) -> u64

Returns the raw u64 value.

pub const fn next(self) -> Self

Returns the next transaction ID.

pub const fn is_valid(self) -> bool

Checks if this is a valid transaction ID.

Trait Implementations

impl Clone for TxId

fn clone(&self) -> TxId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TxId

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

Formats the value using the given formatter.

impl Default for TxId

fn default() -> TxId

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TxId

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for TxId

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

Formats the value using the given formatter.

impl From<TxId> for u64

fn from(id: TxId) -> Self

Converts to this type from the input type.

impl From<u64> for TxId

fn from(id: u64) -> Self

Converts to this type from the input type.

impl Hash for TxId

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 Ord for TxId

fn cmp(&self, other: &TxId) -> 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,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for TxId

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

impl PartialOrd for TxId

fn partial_cmp(&self, other: &TxId) -> 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 Serialize for TxId

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for TxId

impl Eq for TxId
