Source
pub struct ConvertMiddleware<T, T2, A, B, C> { /* private fields */ }
Expand description

Encapsulates the conversion between two different transform types

Trait Implementations§

Source§

impl<T, T2, A, B, C> Middleware<A, C> for ConvertMiddleware<T, T2, A, B, C>
where T: Send + Sync + 'static, T2: Send + Sync + 'static, A: Send + Sync + 'static, B: Send + Sync + 'static, C: Send + Sync + 'static,

Implements the middleware trait on the conversion middleware to make it A -> C

fn call<'life0, 'async_trait>( &'life0 self, input: A, ) -> Pin<Box<dyn Future<Output = C> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Source§

impl<T, T2, A, B, C> Transform<(A, C), A, C> for ConvertMiddleware<T, T2, A, B, C>
where T: Send + Sync + 'static, T2: Send + Sync + 'static, A: Send + Sync + 'static, B: Send + Sync + 'static, C: Send + Sync + 'static,

Implements the transform trait on the conversion middleware (for downstream)

Source§

fn transform<'life0, 'async_trait>( &'life0 self, input: A, ) -> Pin<Box<dyn Future<Output = C> + Send + 'async_trait>>
