# Trait actix_web::actix::actix::dev::ToEnvelope [−]

    pub trait ToEnvelope<A, M> where
        A: Actor + Handler<M>,
        M: Message,
        <A as Actor>::Context: ToEnvelope<A, M>, {
        fn pack(msg: M, tx: Option<Sender<<M as Message>::Result>>) -> Envelope<A>;
    }

Converter trait, packs message to suitable envelope

## Required Methods

### `fn pack(msg: M, tx: Option<Sender<<M as Message>::Result>>) -> Envelope<A>`

Pack message into suitable envelope

## Implementors

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
