Enum HeaderForm 

#[repr(u8)]
pub enum HeaderForm {
    Raw = 0,
    Text = 1,
    Addresses = 2,
    MessageIds = 3,
    CommaList = 4,
    Date = 5,
    ContentType = 6,
    Received = 7,
    Ignore = 8,
}

How a header value is parsed.

Variants

Raw = 0

The value as written, without leading and trailing whitespace.

Text = 1

Unstructured text with RFC 2047 encoded words decoded.

Addresses = 2

An address list: mailboxes and groups in document order.

MessageIds = 3

A list of message identifiers.

CommaList = 4

A comma-separated list of phrases.

Date = 5

An RFC 5322 date.

ContentType = 6

A Content-Type or Content-Disposition value.

Received = 7

A Received trace field.

Ignore = 8

Not parsed; the header is kept with an empty value.

Implementations

impl HeaderForm

pub fn parse(self, value: &[u8]) -> ParsedValue<'_>

Parses a standalone header value: the bytes after the colon, up to the end of the field (a line break not followed by white space).

use mail_parser::HeaderForm;

let parsed = HeaderForm::Addresses.parse(b" Jane <jane@example.com>, bob@example.com\r\n");
let addresses = parsed.value().as_address().expect("addresses");
assert_eq!(addresses.mailboxes().count(), 2);

let parsed = HeaderForm::Date.parse(b" Sat, 20 Nov 2021 14:22:01 -0800\r\n");
let date = parsed.value().as_datetime().expect("date");
assert_eq!(date.to_timestamp(), 1_637_446_921);
