Struct rdms::Empty

pub struct Empty;

Empty value, can be used for indexing entries that have a key but no value.

Trait Implementations

impl Diff for Empty

type D = Empty

fn diff(&self, _a: &Self) -> Self::D

D = C - P

fn merge(&self, _a: &Self::D) -> Self

P = C - D

impl Footprint for Empty

fn footprint(&self) -> isize

impl Serialize for Empty

fn encode(&self, _buf: &mut Vec<u8>) -> usize

Convert this value into binary equivalent. Encoded bytes shall be appended to the input-buffer buf. Return bytes encoded.

fn decode(&mut self, _buf: &[u8]) -> Result<usize, Error>

Reverse process of encode, given the binary equivalent buf, construct self.

impl Clone for Empty

fn clone(&self) -> Empty

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Empty

impl Default for Empty

fn default() -> Empty

Returns the "default value" for a type.

impl Eq for Empty

impl PartialEq<Empty> for Empty

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

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

#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl Debug for Empty

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

Formats the value using the given formatter.
