Trait MiddlewareLike

pub trait MiddlewareLike<TLayerCtx>: Clone {
    type State: Clone + Send + Sync + 'static;
    type NewCtx: Send + 'static;

    // Required method
    fn handle<TMiddleware: Layer<Self::NewCtx> + 'static>(
        &self,
        ctx: TLayerCtx,
        input: Value,
        req: RequestContext,
        next: Arc<TMiddleware>,
    ) -> Result<LayerResult, ExecError>;
}

Required Associated Types

type State: Clone + Send + Sync + 'static

type NewCtx: Send + 'static

Required Methods

fn handle<TMiddleware: Layer<Self::NewCtx> + 'static>( &self, ctx: TLayerCtx, input: Value, req: RequestContext, next: Arc<TMiddleware>, ) -> Result<LayerResult, ExecError>

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.
