Trait ExtractorHandler 

pub trait ExtractorHandler<S, T>:
    Clone
    + Send
    + Sync
    + 'static {
    type Future: Future<Output = Result<CallToolResult>> + Send;

    // Required methods
    fn call(self, ctx: RequestContext, state: S, args: Value) -> Self::Future;
    fn input_schema() -> Value;
}

A handler that uses extractors.

This trait is implemented for functions that take extractors as arguments. You don’t need to implement this trait directly; it’s automatically implemented for compatible async functions.

Required Associated Types

type Future: Future<Output = Result<CallToolResult>> + Send

The future returned by the handler.

Required Methods

fn call(self, ctx: RequestContext, state: S, args: Value) -> Self::Future

Call the handler with extracted values.

fn input_schema() -> Value

Get the input schema for this handler.

Returns None if no Json<T> extractor is used.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
