Struct ArgumentRefusal 

#[non_exhaustive]
pub struct ArgumentRefusal { /* private fields */ }

An ArgumentValidator’s refusal of one tools/call.

Carries the same implementation-supplied-message residual as PolicyRefusal: the message reaches the MCP client and is authored by the validator, so it must be a FIXED string carrying no argument value (T-128-40).

Implementations

impl ArgumentRefusal

pub fn new(message: impl Into<String>) -> Self

Refuse the call with a fixed message.

pub fn message(&self) -> &str

The validator-supplied message, verbatim.

impl Eq for ArgumentRefusal

impl Error for ArgumentRefusal

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
