A representation of a group address. It has a name and
a list of mailboxes.
A simple wrapper around Vec<MailAddr>
. This is primarily here so we can
implement the Display trait on it, and allow user code to easily convert
the return value from addrparse
back into a string. However there are some
additional utility functions on this wrapper as well.
A struct that represents a single header in the message.
It holds slices into the raw byte array passed to parse_mail, and so the
lifetime of this struct must be contained within the lifetime of the raw
input. There are additional accessor functions on this struct to extract
the data as Rust strings.
A simple wrapper around Vec<String>
. This is primarily here so we can
implement the Display trait on it, and allow user code to easily convert
the return value from msgidparse
back into a string. This also allows
to add additional methods on this type in the future.
A struct to hold a more structured representation of the Content-Disposition header.
This is provided mostly as a convenience since this metadata is usually
needed to interpret the message body properly.
A struct to hold a more structured representation of the Content-Type header.
This is provided mostly as a convenience since this metadata is usually
needed to interpret the message body properly.
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.
A representation of a single mailbox. Each mailbox has
a routing address addr
and an optional display name.
Convert an address field from an email header into a structured type.
This function handles the most common formatting of to/from/cc/bcc fields
found in email headers. Note that if you are attempting to parse the
value of a MailHeader
, it is better (both for correctness and performance
to use the addrparse_header
function instead of this one. Correctness
is impacted because of the way encoded words within the header are
processed; using MailHeader::get_value()
will decode encoded words,
which may then contain characters like commas that affect how addrparse
parses the value. This can produce incorrect results in some cases; using
addrparse_header
will avoid this problem.
Take a MailHeader
that contains addresses in the value (e.g. from/to/cc/bcc)
and produce a structured type representing those addresses.
Convert a date field from an email header into a UNIX epoch timestamp.
This function handles the most common formatting of date fields found in
email headers. It may fail to parse some of the more creative formattings.
Parse an email header into a structured type holding a list of message ids.
This function can be used to parse headers containing message IDs, such as
Message-ID
, In-Reply-To
, and References
.
This function is currently mostly trivial (splits on whitespace and strips
angle-brackets) but may be enhanced in the future to strip comments (which
are technically allowed by the RFCs but never really used in practice).
Helper method to parse a header value as a Content-Disposition header. The disposition
defaults to “inline” if no disposition parameter is provided in the header
value.
Helper method to parse a header value as a Content-Type header. Note that
the returned object’s params
map will contain a charset key if a charset
was explicitly specified in the header; otherwise the params
map will not
contain a charset key. Regardless, the charset
field will contain a
charset - either the one explicitly specified or the default of “us-ascii”.
Parse a single header from the raw data given.
This function takes raw byte data, and starts parsing it, expecting there
to be a MIME header key-value pair right at the beginning. It parses that
header and returns it, along with the index at which the next header is
expected to start. If you just want to parse a single header, you can ignore
the second component of the tuple, which is the index of the next header.
Error values are returned if the data could not be successfully interpreted
as a MIME key-value pair.
Parses all the headers from the raw data given.
This function takes raw byte data, and starts parsing it, expecting there
to be zero or more MIME header key-value pair right at the beginning,
followed by two consecutive newlines (i.e. a blank line). It parses those
headers and returns them in a vector. The normal vector functions can be
used to access the headers linearly, or the MailHeaderMap trait can be used
to access them in a map-like fashion. Along with this vector, the function
returns the index at which the message body is expected to start. If you
just care about the headers, you can ignore the second component of the
returned tuple.
Error values are returned if there was some sort of parsing error.
The main mail-parsing entry point.
This function takes the raw data making up the message body and returns a
structured version of it, which allows easily accessing the header and body
information as needed.
