Struct deltachat::message::MsgId

source ·
pub struct MsgId(u32);
Expand description

Message ID, including reserved IDs.

Some message IDs are reserved to identify special message types. This type can represent both the special as well as normal messages.

Implementations§

source§

impl MsgId

source

pub async fn download_full(self, context: &Context) -> Result<()>

Schedules full message download for partially downloaded message.

source

pub(crate) async fn update_download_state( self, context: &Context, download_state: DownloadState ) -> Result<()>

source§

impl MsgId

source

pub(crate) async fn ephemeral_timer(self, context: &Context) -> Result<Timer>

Returns ephemeral message timer value for the message.

source

pub(crate) async fn start_ephemeral_timer(self, context: &Context) -> Result<()>

Starts ephemeral message timer for the message if it is not started yet.

source§

impl MsgId

source

pub fn new(id: u32) -> MsgId

Create a new MsgId.

source

pub fn new_unset() -> MsgId

Create a new unset MsgId.

source

pub fn is_special(self) -> bool

Whether the message ID signifies a special message.

This kind of message ID can not be used for real messages.

source

pub fn is_unset(self) -> bool

Whether the message ID is unset.

When a message is created it initially has a ID of 0, which is filled in by a real message ID once the message is saved in the database. This returns true while the message has not been saved and thus not yet been given an actual message ID.

When this is true, MsgId::is_special will also always be true.

source

pub async fn get_state(self, context: &Context) -> Result<MessageState>

Returns message state.

source

pub async fn trash(self, context: &Context) -> Result<()>

Put message into trash chat and delete message text.

It means the message is deleted locally, but not on the server. We keep some infos to

  1. not download the same message again
  2. be able to delete the message on the server if we want to
source

pub(crate) async fn delete_from_db(self, context: &Context) -> Result<()>

Deletes a message, corresponding MDNs and unsent SMTP messages from the database.

source

pub(crate) async fn set_delivered(self, context: &Context) -> Result<()>

source

pub fn to_u32(self) -> u32

Bad evil escape hatch.

Avoid using this, eventually types should be cleaned up enough that it is no longer necessary.

source

pub async fn rawtext(self, context: &Context) -> Result<String>

Returns raw text of a message, used for message info

source

pub async fn get_info_server_urls( context: &Context, rfc724_mid: String ) -> Result<Vec<String>>

Returns server foldernames and UIDs of a message, used for message info

source

pub async fn hop_info(self, context: &Context) -> Result<Option<String>>

Returns information about hops of a message, used for message info

source

pub async fn get_info(self, context: &Context) -> Result<String>

Returns detailed message information in a multi-line text form.

source§

impl MsgId

source

pub async fn get_html(self, context: &Context) -> Result<Option<String>>

Get HTML by database message id. This requires mime_headers field to be set for the message; this is the case at least when Message.has_html() returns true (we do not save raw mime unconditionally in the database to save space). The corresponding ffi-function is dc_get_msg_html().
