Struct SamplingResponse 

#[non_exhaustive]
pub struct SamplingResponse {
    pub role: String,
    pub content: SamplingContent,
    pub model: String,
    pub stop_reason: Option<String>,
}

The sampling/createMessage response envelope returned by an MCP client. Carries the generated message, the model the client actually used, and an optional stopReason describing why generation halted.

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.

role: String

Speaker role of the generated message. Typically "assistant".

content: SamplingContent

Generated content payload.

model: String

Identifier of the model the client used to generate content. May differ from any hint the server supplied.

stop_reason: Option<String>

Optional reason generation stopped (e.g. "endTurn", "maxTokens", "stopSequence"). Wire field is camelCase stopReason.
