Trait PreToolHook 

pub trait PreToolHook: Send + Sync {
    // Required methods
    fn name(&self) -> &str;
    fn before_tool_call<'life0, 'life1, 'life2, 'async_trait>(
        &'life0 self,

Hook that can block tool execution based on custom logic

Required Methods

fn name(&self) -> &str

fn before_tool_call<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, name: &'life1 str, arguments: &'life2 str, ) -> Pin<Box<dyn Future<Output = HookDecision> + Send + 'async_trait>>

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

Dyn Compatibility

This trait is dyn compatible.

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