Enum RequestId 

pub enum RequestId {
    String(String),
    Number(i64),
    Null,
}

Request ID for JSON-RPC messages.

Can be a string, number, or null according to JSON-RPC 2.0 specification. MCP typically uses string IDs for better traceability.

Variants

String(String)

String identifier

Number(i64)

Numeric identifier

Null

Null identifier (discouraged in MCP)

Trait Implementations

impl Clone for RequestId

fn clone(&self) -> RequestId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RequestId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RequestId

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for RequestId

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

Formats the value using the given formatter.

impl From<&str> for RequestId

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<String> for RequestId

fn from(s: String) -> Self

Converts to this type from the input type.

impl From<i32> for RequestId

fn from(n: i32) -> Self

Converts to this type from the input type.

impl From<i64> for RequestId

fn from(n: i64) -> Self

Converts to this type from the input type.

impl Hash for RequestId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for RequestId

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

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 RequestId
