Implementations

impl RemoteMapping

pub fn new(remote: LSN, local: LSN) -> Self

pub fn lsn(&self) -> Option<LSN>

pub fn local(&self) -> Option<LSN>

pub fn splat(&self) -> Option<(LSN, LSN)>

returns the remote -> local LSN mapping as a single option tuple

Trait Implementations

impl Clone for RemoteMapping

fn clone(&self) -> RemoteMapping

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for RemoteMapping

fn default() -> Self

Returns the “default value” for a type.

impl IntoBytes for RemoteMapping

where [u8; 23]: IntoBytes, [u8; 7]: IntoBytes, LSN: IntoBytes, (): PaddingFree<Self, { _ }>,

fn as_bytes(&self) -> &[u8]

where Self: Immutable,

Gets the bytes of this value.

fn write_to(&self, dst: &mut [u8]) -> Result<(), SizeError<&Self, &mut [u8]>>

where Self: Immutable,

Writes a copy of self to dst.

fn write_to_prefix( &self, dst: &mut [u8], ) -> Result<(), SizeError<&Self, &mut [u8]>>

where Self: Immutable,

Writes a copy of self to the prefix of dst.

fn write_to_suffix( &self, dst: &mut [u8], ) -> Result<(), SizeError<&Self, &mut [u8]>>

where Self: Immutable,

Writes a copy of self to the suffix of dst.

impl KnownLayout for RemoteMapping

where Self: Sized,

type PointerMetadata = ()

The type of metadata stored in a pointer to Self.

impl PartialEq for RemoteMapping

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
