Trait ExecutorAdapter 

pub trait ExecutorAdapter: Send + Sync {
    // Required method
    fn execute_with_context<'a>(
        &'a self,
        query: &'a str,
        variables: Option<&'a Value>,
        ctx: &'a ExecutionContext,
    ) -> Pin<Box<dyn Future<Output = Result<String>> + Send + 'a>>;
}

Type-erased executor interface.

Allows code that drives query execution (fraiseql-server, tests) to hold Arc<dyn ExecutorAdapter> without being generic over DatabaseAdapter.

Concrete implementations should implement this trait on their Executor<A> type to participate in the type-erased execution path.

Required Methods

fn execute_with_context<'a>( &'a self, query: &'a str, variables: Option<&'a Value>, ctx: &'a ExecutionContext, ) -> Pin<Box<dyn Future<Output = Result<String>> + Send + 'a>>

Execute a GraphQL query string with an execution context.

Arguments

• query — the raw GraphQL query document
• variables — optional JSON object of query variables
• ctx — execution context carrying the query ID and cancellation token

Returns

A JSON-serialised GraphQL response string on success.

Errors

Returns a crate::error::FraiseQLError if parsing, validation, or SQL execution fails, or if the context’s cancellation token has already been triggered.
