Struct EventBody 

pub struct EventBody {
    pub kind: EventKind,
    pub payload: Value,
}

The kind and the payload, as the log holds them.

The pair {"kind": .., "payload": ..}: the kind is the name a payload type declares, and the payload is that type’s value, held as JSON so that a body under a kind this crate has never heard of is carried rather than refused.

Fields

kind: EventKind

Which event this is.

payload: Value

What it carries, in the form its kind declares.

Implementations

impl EventBody

pub fn of<P: EventPayload>(payload: &P) -> Result<Self, Error>

The body of one typed payload, under the kind its type declares.

Errors

Returns the serialization failure when the payload cannot be rendered as JSON, which a payload type declared with serde never is.

pub fn is<P: EventPayload>(&self) -> bool

Whether this body is under the kind P declares.

pub fn read<P: EventPayload>(&self) -> Option<Result<P, Error>>

The payload as P, when this body is under the kind P declares.

Answers nothing for another kind’s body, and the parse failure for a body under the right kind whose payload is not of the type.

Trait Implementations

impl Clone for EventBody

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EventBody

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EventBody

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for EventBody

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for EventBody

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

Equality operator ==.

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

Inequality operator !=.

impl Sample for EventBody

fn sample_full() -> Self

A value carrying every field the type declares.

fn sample_minimal() -> Self

A value carrying every optional field absent.

fn sample_alternates() -> Vec<Self>

One value per further arm, for a type whose wire form is a union.

impl Serialize for EventBody

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
