Enum HookOutcome 

#[non_exhaustive]
pub enum HookOutcome {
    Continue,
    Deny(ErrorData),
    Replace(Box<CallToolResult>),
}

Outcome returned by a BeforeHook to control invocation flow.

• HookOutcome::Continue - proceed with the wrapped handler.
• HookOutcome::Deny - reject the call with the supplied ErrorData; the inner handler is not called.
• HookOutcome::Replace - return the supplied result instead of invoking the inner handler. The result is still subject to max_result_bytes capping.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Continue

Proceed with the wrapped handler.

Deny(ErrorData)

Reject the call. The error is propagated to the client as-is.

Replace(Box<CallToolResult>)

Skip the inner handler and return the supplied result instead.
