## Example: Parsing bytes into an `Envelope`
|
|
|
|
An `Envelope` represents the information you can get from an email's headers
|
|
and body structure. Addresses in `To`, `From` fields etc are parsed into
|
|
`Address` types.
|
|
|
|
```rust
|
|
use melib::{Attachment, Envelope};
|
|
|
|
let raw_mail = r#"From: "some name" <some@address.com>
|
|
To: "me" <myself@i.tld>
|
|
Cc:
|
|
Subject: =?utf-8?Q?gratuitously_encoded_subject?=
|
|
Message-ID: <h2g7f.z0gy2pgaen5m@address.com>
|
|
MIME-Version: 1.0
|
|
Content-Type: multipart/mixed; charset="utf-8";
|
|
boundary="bzz_bzz__bzz__"
|
|
|
|
This is a MIME formatted message with attachments. Use a MIME-compliant client to view it properly.
|
|
--bzz_bzz__bzz__
|
|
|
|
hello world.
|
|
--bzz_bzz__bzz__
|
|
Content-Type: image/gif; name="test_image.gif"; charset="utf-8"
|
|
Content-Disposition: attachment
|
|
Content-Transfer-Encoding: base64
