pub struct ToolInvocation {
    pub invocation_id: String,
    pub session_id: String,
    pub server_id: String,
    pub tool_name: String,
    pub args: Value,
    pub descriptor_hash: String,
    pub requested_at: i64,
}

Fields

invocation_id: String

唯一 id（UUIDv4 文本）。

session_id: String

归属 session。

server_id: String

目标 server。

tool_name: String

upstream 工具名。

args: Value

原始参数（来自 MCP tools/call 的 arguments 字段）。

requested_at: i64

请求到达时间（Unix epoch 秒）。

Trait Implementations

impl Clone for ToolInvocation

fn clone(&self) -> ToolInvocation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ToolInvocation

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ToolInvocation

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for ToolInvocation

impl PartialEq for ToolInvocation

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
