Struct CustomNotification 

pub struct CustomNotification {
    pub method: String,
    pub params: Option<Value>,
    pub extensions: Extensions,
}

Available on crate features mcp and tools only.

A catch-all notification either side can use to send custom messages to its peer.

This preserves the raw method name and params payload so handlers can deserialize them into domain-specific types.

Fields

method: String

params: Option<Value>

extensions: Extensions

extensions will carry anything possible in the context, including the metadata (RequestMetaObject for requests, NotificationMetaObject for notifications)

this is similar with the Extensions in http crate

Implementations

impl CustomNotification

pub fn new( method: impl Into<String>, params: Option<Value>, ) -> CustomNotification

pub fn params_as<T>(&self) -> Result<Option<T>, Error>

where T: DeserializeOwned,

Deserialize params into a strongly-typed structure.

Trait Implementations

impl Clone for CustomNotification

fn clone(&self) -> CustomNotification

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CustomNotification

fn deserialize<D>( deserializer: D, ) -> Result<CustomNotification, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<CustomNotification> for ClientNotification

fn from(value: CustomNotification) -> ClientNotification

Converts to this type from the input type.

impl From<CustomNotification> for ServerNotification

fn from(value: CustomNotification) -> ServerNotification

Converts to this type from the input type.

impl GetExtensions for CustomNotification

fn get_meta(&self) -> &NotificationMetaObject

impl JsonSchema for CustomNotification

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 Serialize for CustomNotification

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.
