Trait Guard 

pub trait Guard: Send + Sync {
    // Required methods
    fn name(&self) -> &str;
    fn evaluate(
        &self,
        ctx: &GuardContext<'_>,
    ) -> Result<GuardDecision, KernelError>;
}

Required Methods

fn name(&self) -> &str

Human-readable guard name (e.g., “forbidden-path”).

fn evaluate(&self, ctx: &GuardContext<'_>) -> Result<GuardDecision, KernelError>

Evaluate the guard against a tool call request.

Returns an allow or deny decision with optional evidence, or Err on internal failure (which the kernel treats as deny).

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
