Trait CompletionHandler 

pub trait CompletionHandler: Send + Sync {
    // Required methods
    fn complete_resource(
        &self,
        partial_uri: &str,
        ctx: &Context<'_>,
    ) -> impl Future<Output = Result<Vec<String>, McpError>> + Send;
    fn complete_prompt_arg(
        &self,
        prompt_name: &str,
        arg_name: &str,
        partial_value: &str,
        ctx: &Context<'_>,
    ) -> impl Future<Output = Result<Vec<String>, McpError>> + Send;
}

Handler for completion suggestions.

Implement this trait to provide autocomplete suggestions for resource URIs, prompt arguments, etc.

Required Methods

fn complete_resource( &self, partial_uri: &str, ctx: &Context<'_>, ) -> impl Future<Output = Result<Vec<String>, McpError>> + Send

Complete a partial resource URI.

fn complete_prompt_arg( &self, prompt_name: &str, arg_name: &str, partial_value: &str, ctx: &Context<'_>, ) -> impl Future<Output = Result<Vec<String>, McpError>> + Send

Complete a partial prompt argument.

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.
