Trait Implementations

impl Clone for PgLsn

fn clone(&self) -> PgLsn

Returns a copy 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 From<PgLsn> for u64

fn from(lsn: PgLsn) -> u64

Converts to this type from the input type.

impl From<u64> for PgLsn

fn from(lsn_u64: u64) -> Self

Converts to this type from the input type.

impl<'a> FromSql<'a> for PgLsn

fn from_sql( _: &Type, raw: &'a [u8] ) -> Result<Self, Box<dyn Error + Sync + Send>>

Creates a new value of this type from a buffer of data of the specified Postgres Type in its binary format.

fn accepts(ty: &Type) -> bool

Determines if a value of this type can be created from the specified Postgres Type.

fn from_sql_null(ty: &Type) -> Result<Self, Box<dyn Error + Sync + Send>>

Creates a new value of this type from a NULL SQL value.

fn from_sql_nullable( ty: &Type, raw: Option<&'a [u8]> ) -> Result<Self, Box<dyn Error + Sync + Send>>

A convenience function that delegates to from_sql and from_sql_null depending on the value of raw.

impl FromStr for PgLsn

type Err = ParseLsnError

The associated error which can be returned from parsing.

fn from_str(lsn_str: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for PgLsn

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

This method tests for self and other values to be equal, and is used by ==.

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

This method 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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl ToSql for PgLsn

fn to_sql( &self, _: &Type, out: &mut BytesMut ) -> Result<IsNull, Box<dyn Error + Sync + Send>>

Converts the value of self into the binary format of the specified Postgres Type, appending it to out.

fn accepts(ty: &Type) -> bool

Determines if a value of this type can be converted to the specified Postgres Type.

fn to_sql_checked( &self, ty: &Type, out: &mut BytesMut ) -> Result<IsNull, Box<dyn Error + Sync + Send>>

An adaptor method used internally by Rust-Postgres.

fn encode_format(&self, _ty: &Type) -> Format

Specify the encode format
