Struct DeniedArgumentPattern 

pub struct DeniedArgumentPattern { /* private fields */ }

Available on crate feature guardrail only.

Denies a call whose serialized arguments match a pattern.

The pattern is matched against the JSON encoding of the whole argument object, so it catches a value wherever it appears rather than requiring the field to be named up front.

Example

use adk_guardrail::{DeniedArgumentPattern, Severity};

let guardrail = DeniedArgumentPattern::new("no-force-push", r"--force\b", Severity::High)?
    .on_tools(["run_command"]);

Implementations

impl DeniedArgumentPattern

pub fn new( name: impl Into<String>, pattern: &str, severity: Severity, ) -> Result<DeniedArgumentPattern, Error>

Creates a guardrail denying calls whose arguments match pattern.

Errors

Returns an error if pattern is not a valid regular expression.

pub fn on_tools<I, S>(self, tools: I) -> DeniedArgumentPattern

where I: IntoIterator<Item = S>, S: Into<String>,

Restricts this guardrail to the named tools. Without this it applies to every tool.

Trait Implementations

impl ToolGuardrail for DeniedArgumentPattern

fn name(&self) -> &str

Unique name, used in denial messages and logs.

fn applies_to(&self, tool_name: &str) -> bool

Whether this guardrail applies to tool_name. Defaults to every tool.

fn validate_call<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, tool_name: &'life1 str, args: &'life2 Value, ) -> Pin<Box<dyn Future<Output = ToolGuardrailResult> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, DeniedArgumentPattern: 'async_trait,

Validates a call to tool_name with args.
