Struct JsonMapMetadata 

pub struct JsonMapMetadata(/* private fields */);

A simple wrapper around a JSON map to represent task metadata

Trait Implementations

impl Clone for JsonMapMetadata

fn clone(&self) -> JsonMapMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JsonMapMetadata

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

Formats the value using the given formatter.

impl Default for JsonMapMetadata

fn default() -> JsonMapMetadata

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for JsonMapMetadata

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T: Serialize + for<'de> Deserialize<'de>> MetadataExt<T> for JsonMapMetadata

type Error = Error

The error type that can occur during extraction or injection.

fn extract(&self) -> Result<T, Error>

Extract metadata of type T.

fn inject(&mut self, value: T) -> Result<(), Error>

Inject metadata of type T.

impl PartialEq for JsonMapMetadata

fn eq(&self, other: &JsonMapMetadata) -> 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 JsonMapMetadata

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for JsonMapMetadata
