Enum ToolResult 

pub enum ToolResult {
    Done,
    Text {
        text: String,
    },
    Tsv {
        text: String,
    },
    Json {
        value: Value,
    },
    Binary {
        mime: String,
        content: Vec<u8>,
    },
    Error {
        message: String,
    },
}

Final structured result from a tool execution.

This keeps successful content and tool-level failures in distinct variants so UIs and runtimes do not need to infer errors from free-form strings.

Example

use aither::llm::tool::ToolResult;

fn search_tool() -> ToolResult {
    ToolResult::text("Found 3 results...")
}

fn delete_tool() -> ToolResult {
    ToolResult::Done
}

Variants

Done

Tool completed with no output to return.

Text

UTF-8 plain text output.

Fields

text: String

Plain text content.

Tsv

Tab-separated tabular output.

Fields

text: String

TSV content.

Json

Structured JSON output.

Fields

value: Value

JSON content.

Binary

Binary or media payload.

Fields

mime: String

MIME type of the payload (for example image/png).

content: Vec<u8>

Raw content bytes.

Error

Tool-level error. This is distinct from transport/runtime failures.

Fields

message: String

Tool-level error message.

Implementations

impl ToolResult

pub fn text(s: impl Into<String>) -> Self

Creates a plain text result.

pub fn tsv(s: impl Into<String>) -> Self

Creates a TSV result.

pub fn json<T: Serialize>(value: &T) -> Result<Self>

Creates a JSON result from a serializable value.

Errors

Returns an error if serialization fails.

pub const fn json_value(value: Value) -> Self

Creates a JSON result from an already-materialized JSON value.

pub fn image(data: Vec<u8>, media_type: &str) -> Self

Creates an image result.

pub fn binary(data: Vec<u8>) -> Self

Creates a binary result.

pub fn error(message: impl Into<String>) -> Self

Creates a typed tool error result.

pub const fn is_done(&self) -> bool

Returns true if this is a Done variant.

pub const fn is_error(&self) -> bool

Returns true if this is a typed tool error.

pub fn as_text(&self) -> Option<&str>

Returns plain textual content for text-like variants.

pub fn error_message(&self) -> Option<&str>

Returns the error message if this is a typed tool error.

pub fn render_for_model(&self) -> Result<String>

Projects the result into a textual representation safe to re-inject into model context.

Errors

Returns an error if JSON serialization fails.

pub fn render_for_cli(&self) -> Result<String>

Renders the result for CLI display.

Errors

Returns an error if JSON serialization fails.

pub fn mime(&self) -> Option<Mime>

Parses and returns the MIME type when this result carries binary content.

pub fn content(&self) -> Option<&[u8]>

Returns raw bytes for binary results.
