Struct Context 

pub struct Context {
    pub request_id: String,
    pub tool_use_id: String,
    pub max_result_size: usize,
    /* private fields */
}

Carries per-request metadata and cancellation through tool execution.

Fields

request_id: String

Unique request identifier.

tool_use_id: String

Tool-use identifier (links back to the LLM tool call).

max_result_size: usize

Maximum size (in bytes) for the result content.

Implementations

impl Context

pub fn new() -> Self

Create a context with empty identifiers, no result-size limit, and a fresh cancellation token.

pub fn with_cancellation(token: CancellationToken) -> Self

Create a context that observes the provided cancellation token.

pub fn set(&mut self, key: &str, value: ToolOutput)

Store metadata for the current tool call under key.

pub fn get(&self, key: &str) -> Option<&ToolOutput>

Return metadata previously stored under key, if present.

pub const fn cancel_token(&self) -> &CancellationToken

Return the cancellation token associated with this tool call.

pub fn is_cancelled(&self) -> bool

Return whether cancellation has been requested for this tool call.
