Struct McpSamplingExecutionResult 

pub struct McpSamplingExecutionResult {
    pub action: McpSamplingExecutionAction,
    pub error: Option<String>,
    pub result: Option<McpExecuteSamplingResult>,
}

Outcome of an MCP sampling execution: success result, failure error, or cancellation.

Experimental. This type is part of an experimental wire-protocol surface and may change or be removed in future SDK or CLI releases.

Fields

action: McpSamplingExecutionAction

Outcome of the sampling inference. ‘success’ produced a response; ‘failure’ encountered an error (including agent-side rejection by content filter or criteria); ‘cancelled’ the caller cancelled this execution via cancelSamplingExecution.

error: Option<String>

Error description, present when action=‘failure’.

result: Option<McpExecuteSamplingResult>

MCP CreateMessageResult payload (with optional ‘tools’ extension), present when action=‘success’. Treated as opaque at the schema layer; consumers should construct/consume it per the MCP CreateMessageResult shape.
