Struct mailparse::ParsedMail

pub struct ParsedMail<'a> {
    pub headers: Vec<MailHeader<'a>>,
    pub ctype: ParsedContentType,
    pub subparts: Vec<ParsedMail<'a>>,
    // some fields omitted
}

Struct that holds the structured representation of the message. Note that since MIME allows for nested multipart messages, a tree-like structure is necessary to represent it properly. This struct accomplishes that by holding a vector of other ParsedMail structures for the subparts.

Fields

headers: Vec<MailHeader<'a>>

The headers for the message (or message subpart).

ctype: ParsedContentType

The Content-Type information for the message (or message subpart).

subparts: Vec<ParsedMail<'a>>

The subparts of this message or subpart. This vector is only non-empty if ctype.mimetype starts with “multipart/”.

Implementations

impl<'a> ParsedMail<'a>

pub fn get_body(&self) -> Result<String, MailParseError>

Get the body of the message as a Rust string. This function tries to unapply the Content-Transfer-Encoding if there is one, and then converts the result into a Rust UTF-8 string using the charset in the Content-Type (or “us-ascii” if the charset was missing or not recognized). Note that in some cases the body may be binary data that doesn’t make sense as a Rust string - it is up to the caller to handle those cases gracefully. These cases may occur in particular when the body is of a “binary” Content-Transfer-Encoding (i.e. where get_body_encoded() returns a Body::Binary variant) but may also occur in other cases because of the messiness of the real world and non-compliant mail implementations.

Examples

    use mailparse::parse_mail;
    let p = parse_mail(concat!(
            "Subject: test\n",
            "\n",
            "This is the body").as_bytes())
        .unwrap();
    assert_eq!(p.get_body().unwrap(), "This is the body");

pub fn get_body_raw(&self) -> Result<Vec<u8>, MailParseError>

Get the body of the message as a Rust Vec. This function tries to unapply the Content-Transfer-Encoding if there is one, but won’t do any charset decoding.

Examples

    use mailparse::parse_mail;
    let p = parse_mail(concat!(
            "Subject: test\n",
            "\n",
            "This is the body").as_bytes())
        .unwrap();
    assert_eq!(p.get_body_raw().unwrap(), b"This is the body");

pub fn get_body_encoded(&'a self) -> Body<'a>

Get the body of the message. This function returns the original body without attempting to unapply the Content-Transfer-Encoding. The returned object contains information that allows the caller to control decoding as desired.

Examples

    use mailparse::parse_mail;
    use mailparse::body::Body;

    let mail = parse_mail(b"Content-Transfer-Encoding: base64\r\n\r\naGVsbG 8gd\r\n29ybGQ=").unwrap();

    match mail.get_body_encoded() {
        Body::Base64(body) => {
            assert_eq!(body.get_raw(), b"aGVsbG 8gd\r\n29ybGQ=");
            assert_eq!(body.get_decoded().unwrap(), b"hello world");
            assert_eq!(body.get_decoded_as_string().unwrap(), "hello world");
        },
        _ => assert!(false),
    };


    // An email whose body encoding is not known upfront
    let another_mail = parse_mail(b"").unwrap();

    match another_mail.get_body_encoded() {
        Body::Base64(body) | Body::QuotedPrintable(body) => {
            println!("mail body encoded: {:?}", body.get_raw());
            println!("mail body decoded: {:?}", body.get_decoded().unwrap());
            println!("mail body decoded as string: {}", body.get_decoded_as_string().unwrap());
        },
        Body::SevenBit(body) | Body::EightBit(body) => {
            println!("mail body: {:?}", body.get_raw());
            println!("mail body as string: {}", body.get_as_string().unwrap());
        },
        Body::Binary(body) => {
            println!("mail body binary: {:?}", body.get_raw());
        }
    }

pub fn get_headers(&'a self) -> Headers<'a>

Returns a struct that wraps the headers for this message. The struct provides utility methods to read the individual headers.

pub fn get_content_disposition(&self) -> ParsedContentDisposition

Returns a struct containing a parsed representation of the Content-Disposition header. The first header with this name is used, if there are multiple. See the parse_content_disposition method documentation for more details on the semantics of the returned object.
