Struct RoundToolResult 

#[non_exhaustive]
pub struct RoundToolResult {
    pub tool_use_id: String,
    pub tool_name: String,
    pub is_error: bool,
}

The per-turn steering seam, whole: the trait a host implements and every type its signatures make that host name.

Re-exported rather than wrapped, under the rule stated on CancellationToken — a mentra type basis’s surface asks a caller to write is a name basis re-exports, or the caller pins mentra in their own manifest to spell it. And like the token, a strategy is an identity rather than a value: TurnOptions::with_round_strategy hands mentra the caller’s own Arc, so a basis-owned mirror of RoundDecision would be a translation layer with opinions of its own — the opposite of a seam.

The set is exactly what implementing costs. RoundStrategy is the trait (spelled with async_trait, which basis already re-exports); RoundContext and RoundBoundary are its question; RoundDecision, RoundAdjustment, ReasoningChange and RoundToolResult are its vocabulary for answering. The last three are here because the vocabulary’s own signatures demand them: RoundDecision::inject takes ContentBlocks, RoundAdjustment::with_model a ModelInfo, and ReasoningChange::Set a ReasoningOptions — whose effort field an Effort converts into, so switching effort mid-run never names mentra’s own level enum. Provider-neutral summary of one committed tool result.

Exposes only what a host needs to reason about a completed tool round without coupling to mentra’s internal tool-result representation.

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.

tool_use_id: String

The tool_use_id correlating this result with its originating tool call.

tool_name: String

The name of the tool that produced the result.

is_error: bool

Whether the tool reported an error.
