Writer is a trait allows you to implement custom writing logic for different data types.

Implementing the Writer trait for your data type allows you to use it writing the data to the Response object.

There are several built-in implementations of the Writer trait.

Required Methods

fn write<'life0, 'life1, 'life2, 'async_trait>( self, req: &'life0 mut Request, depot: &'life1 mut Depot, res: &'life2 mut Response ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, Self: 'async_trait,

Write data to Response.

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, Option<P>: 'async_trait,

impl<T, E> Writer for Result<T, E>
