Struct PgLsn 

pub struct PgLsn(pub u64);

PostgreSQL PG_LSN type – a 64-bit Log Sequence Number.

Represents a position in the WAL (write-ahead log). Wire format is 8 bytes, big-endian u64 (sent as i64 on the wire).

Tuple Fields

0: u64

Trait Implementations

impl Clone for PgLsn

fn clone(&self) -> PgLsn

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PgLsn

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

Formats the value using the given formatter.

impl Display for PgLsn

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

Formats the value using the given formatter.

impl FromSql for PgLsn

fn oid() -> Oid

The PostgreSQL type OID this decoder handles.

fn from_sql(buf: &[u8]) -> Result<Self>

Decode from PG binary format.

fn from_sql_nullable(buf: Option<&[u8]>) -> Result<Self>

Decode from a potentially NULL column.

impl Hash for PgLsn

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 PgLsn

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

fn eq(&self, other: &PgLsn) -> 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 PgLsn

fn partial_cmp(&self, other: &PgLsn) -> 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 ToSql for PgLsn

fn oid(&self) -> Oid

The PostgreSQL type OID for this Rust type.

fn to_sql(&self, buf: &mut BytesMut) -> Result<()>

Encode this value into PG binary format, appending to buf.

fn to_sql_vec(&self) -> Result<Vec<u8>>

Encode this value into a standalone byte vector for use as a bind parameter.

fn is_null(&self) -> bool

Returns true if this value represents SQL NULL.
