## Description

## Details

### struct EMailParserExtension

    struct EMailParserExtension;

The EMailParserExtension is an abstract interface for all extensions for EMailParser.

### enum EMailParserExtensionFlags

    typedef enum {
     /*< flags >*/
    	E_MAIL_PARSER_EXTENSION_INLINE = 1 << 0,
    	E_MAIL_PARSER_EXTENSION_INLINE_DISPOSITION = 1 << 1,
    	E_MAIL_PARSER_EXTENSION_COMPOUND_TYPE = 1 << 2
    } EMailParserExtensionFlags;

`E_MAIL_PARSER_EXTENSION_INLINE` | Don't parse as attachment.
`E_MAIL_PARSER_EXTENSION_INLINE_DISPOSITION` | Always expand.
`E_MAIL_PARSER_EXTENSION_COMPOUND_TYPE` | Always check what's inside.

### e_mail_parser_extension_parse ()

    gboolean            e_mail_parser_extension_parse       (EMailParserExtension *extension,
                                                             EMailParser *parser,
                                                             CamelMimePart *mime_part,
                                                             GString *part_id,
                                                             GCancellable *cancellable,
                                                             GQueue *out_mail_parts);

A virtual function reimplemented in all mail parser extensions. The function decodes and parses the `mime_part`, appending one or more EMailPart<!-//>s to the `out_mail_parts` queue.

When the function is unable to parse the `mime_part` (either because it's broken or because it is a different MIME type then the extension is specialized for), the function will return `FALSE` to indicate to the EMailParser that it should pick another extension.

When the `mime_part` contains for example multipart/mixed of one RFC822 message with an attachment and of one image, then parser must make sure that parts are appeded to `out_mail_parts` in the correct order.

part1.rfc822.plain_text part1.rfc822.attachment part2.image

Implementation of this function must be thread-safe.

`extension` : | an EMailParserExtension
`parser` : | a EMailParser
`mime_part` : | (allow-none) a CamelMimePart to parse
`part_id` : | a GString to which parser will append ID of the parsed part.
`cancellable` : | (allow-none) A GCancellable
`out_mail_parts` : | a GQueue to deposit EMailPart instances
Returns : | `TRUE` if the `mime_part` was handled (even if no EMailPart<!-//>s were added to `out_mail_parts`), or `FALSE` if the `mime_part` was not handled
