Struct ToolResult 

pub struct ToolResult {
    pub call_id: String,
    pub tool_name: String,
    pub output: Value,
    pub content: Option<Vec<ToolContent>>,
    pub is_error: bool,
}

Rich tool execution result with typed content.

This is the canonical result type returned by Tool::execute. It includes both a legacy JSON output and optional MCP-style typed content blocks for richer responses.

For the simplified kernel-level outcome, see ToolOutcome.

Fields

call_id: String

tool_name: String

output: Value

Legacy JSON output (always present for backward compatibility).

content: Option<Vec<ToolContent>>

MCP-style typed content blocks (optional, alongside output).

is_error: bool

Whether this result represents an error (MCP: isError).

Implementations

impl ToolResult

pub fn text( call_id: impl Into<String>, tool_name: impl Into<String>, text: &str, ) -> Self

Create a successful text result.

pub fn json( call_id: impl Into<String>, tool_name: impl Into<String>, value: Value, ) -> Self

Create a successful JSON result.

pub fn error( call_id: impl Into<String>, tool_name: impl Into<String>, message: &str, ) -> Self

Create an error result.

Trait Implementations

impl Clone for ToolResult

fn clone(&self) -> ToolResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ToolResult

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ToolResult

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&ToolResult> for ToolOutcome

Convert a rich ToolResult to a simplified ToolOutcome for kernel boundaries.

fn from(result: &ToolResult) -> Self

Converts to this type from the input type.

impl PartialEq for ToolResult

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
