Enum TraceEntry 

pub enum TraceEntry {
    ListTools {
        failure_reason: Option<String>,
    },
    ToolCall {
        invocation: ToolInvocation,
        response: Option<CallToolResult>,
        failure_reason: Option<String>,
    },
}

A trace entry capturing MCP interactions.

Variants

ListTools

A list-tools request was issued.

Fields

failure_reason: Option<String>

Optional failure detail when list-tools fails.

ToolCall

A tool call, optionally annotated with a response on failure.

Fields

invocation: ToolInvocation

The invocation that was sent.

response: Option<CallToolResult>

Optional response payload (omitted in compact traces).

failure_reason: Option<String>

Optional failure detail when a call fails.

Implementations

impl TraceEntry

pub fn list_tools() -> Self

Creates a trace entry for a list-tools call.

pub fn list_tools_with_failure(reason: String) -> Self

Creates a trace entry for a failed list-tools call.

pub fn tool_call(invocation: ToolInvocation) -> Self

Creates a trace entry for a tool call without a response.

pub fn tool_call_with_response( invocation: ToolInvocation, response: CallToolResult, ) -> Self

Creates a trace entry for a tool call with a response.

pub fn as_tool_call(&self) -> Option<(&ToolInvocation, Option<&CallToolResult>)>

Returns the invocation and response when the entry is a tool call.

Trait Implementations

impl Clone for TraceEntry

fn clone(&self) -> TraceEntry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TraceEntry

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TraceEntry

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for TraceEntry

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 TraceEntry

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
