Enum Handler 

pub enum Handler {
    Static(Response),
    Dynamic(Arc<dyn Fn(&Request) -> Response + Send + Sync>),
}

Variants

Static(Response)

Static response - always returns the same response

Dynamic(Arc<dyn Fn(&Request) -> Response + Send + Sync>)

Dynamic response - builds response based on the request

Implementations

impl Handler

pub fn new(response: Response) -> Self

Create a new static handler with a predefined response

pub fn dynamic<F>(f: F) -> Self

where F: Fn(&Request) -> Response + Send + Sync + 'static,

Create a dynamic handler that builds responses based on the request

pub fn from_json<T: Serialize>(value: &T) -> Self

Create a static handler from a JSON value

pub fn with_status(self, status: u16) -> Self

Modify the status code (only works for static handlers, returns a new static handler)

pub fn with_header( self, key: impl Into<String>, value: impl Into<String>, ) -> Self

Add a header (only works for static handlers)

pub fn respond(&self, request: &Request) -> Response

Get the response for a given request

pub fn response(&self) -> Response

Get the static response (for backwards compatibility) Returns a default response for dynamic handlers
