Trait FromRequest

pub trait FromRequest: Sized {
    // Required method
    fn from_request<'life0, 'async_trait>(
        req: &'life0 RequestObjectWithData,
    ) -> Pin<Box<dyn Future<Output = Result<Self, Error>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}

A trait to extract data from the request

Required Methods

fn from_request<'life0, 'async_trait>( req: &'life0 RequestObjectWithData, ) -> Pin<Box<dyn Future<Output = Result<Self, Error>> + Send + 'async_trait>>

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

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.
