Struct Empty

pub struct Empty {}

When used with serde this will serialize to an empty JSON object ({})

Some remarks about this struct:

• We use Empty {} and not Empty, because they serialize differently {} vs explicit null
• We don’t make this non_exhaustive since we will never add fields to it, and using Empty {} makes a a bit more clear that we are making an empty struct (object)
• In most cases you don’t want to use this struct directly but instead you want to use NO_PAYLOAD or EMPTY_PAYLOAD

Trait Implementations

impl Debug for Empty

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Empty

fn deserialize<__D>( __deserializer: __D, ) -> Result<Empty, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Empty

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Empty

impl StructuralPartialEq for Empty
