Struct CreateMessageResult 

#[non_exhaustive]
pub struct CreateMessageResult {
    pub model: String,
    pub stop_reason: Option<String>,
    pub message: SamplingMessage,
}

👎Deprecated since 2.0.0:

Sampling is deprecated by SEP-2577 and will be removed in a future release. See https://github.com/modelcontextprotocol/modelcontextprotocol/pull/2577

Available on crate features mcp and tools only.

Result of sampling/createMessage (SEP-1577). The result of a sampling/createMessage request containing the generated response.

This structure contains the generated message along with metadata about how the generation was performed and why it stopped.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

model: String

Sampling is deprecated by SEP-2577 and will be removed in a future release. See https://github.com/modelcontextprotocol/modelcontextprotocol/pull/2577

The identifier of the model that generated the response

stop_reason: Option<String>

The reason why generation stopped (e.g., “endTurn”, “maxTokens”)

message: SamplingMessage

Implementations

impl CreateMessageResult

pub const STOP_REASON_END_TURN: &'static str = "endTurn"

pub const STOP_REASON_END_SEQUENCE: &'static str = "stopSequence"

pub const STOP_REASON_END_MAX_TOKEN: &'static str = "maxTokens"

pub const STOP_REASON_TOOL_USE: &'static str = "toolUse"

pub fn new(message: SamplingMessage, model: String) -> CreateMessageResult

Create a new CreateMessageResult with required fields.

pub fn with_stop_reason( self, stop_reason: impl Into<String>, ) -> CreateMessageResult

Set the stop reason.

pub fn with_model(self, model: impl Into<String>) -> CreateMessageResult

Set the model identifier.

pub fn validate(&self) -> Result<(), String>

Validate the result per SEP-1577: role must be “assistant”.
