Struct TransformMiddleware 

pub struct TransformMiddleware<BeforeFn, AfterFn>
where
    BeforeFn: Fn(Value) -> Result<Value> + Send + Sync,
    AfterFn: Fn(Value) -> Result<Value> + Send + Sync,
{ /* private fields */ }

Transform middleware - applies transformations to request/response

Implementations

impl<BeforeFn, AfterFn> TransformMiddleware<BeforeFn, AfterFn>

where BeforeFn: Fn(Value) -> Result<Value> + Send + Sync, AfterFn: Fn(Value) -> Result<Value> + Send + Sync,

Trait Implementations

impl<BeforeFn, AfterFn> Middleware for TransformMiddleware<BeforeFn, AfterFn>

where BeforeFn: Fn(Value) -> Result<Value> + Send + Sync, AfterFn: Fn(Value) -> Result<Value> + Send + Sync,

fn before<'life0, 'async_trait>( &'life0 self, request: Value, ) -> Pin<Box<dyn Future<Output = Result<Value>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Process request before handler execution Returns modified request or error

fn after<'life0, 'async_trait>( &'life0 self, _request: Value, response: Value, ) -> Pin<Box<dyn Future<Output = Result<Value>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Process response after handler execution Returns modified response or error

fn on_error<'life0, 'async_trait>( &'life0 self, request: Value, error: Error, ) -> Pin<Box<dyn Future<Output = Result<Value>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Handle errors from handler or downstream middleware
