Trait Resolver 

pub trait Resolver: Send + Sync {
    // Required method
    fn resolve<'a>(
        &'a self,
        query: &'a Query,
        ctx: &'a Context,
    ) -> Pin<Box<dyn Future<Output = Result<Response, Error>> + Send + 'a>>;
}

Resolver for queries against a resource. Implementations are domain-specific (storage, analysis, telemetry).

This trait is dyn-compatible: resolve returns a boxed future so that transport adapters can hold Arc<dyn Resolver>.

Required Methods

fn resolve<'a>( &'a self, query: &'a Query, ctx: &'a Context, ) -> Pin<Box<dyn Future<Output = Result<Response, Error>> + Send + 'a>>

Resolve a query against this resolver’s resource.

Errors

Returns Error if the query cannot be fulfilled.

Dyn Compatibility

This trait is dyn compatible.

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