Struct deltachat::contact::ContactId

source · 
pub struct ContactId(u32);
Expand description

Contact ID, including reserved IDs.

Some contact IDs are reserved to identify special contacts. This type can represent both the special as well as normal contacts.

Tuple Fields§

§0: u32

Implementations§

source§

impl ContactId

source

pub const UNDEFINED: ContactId = _

Undefined contact. Used as a placeholder for trashed messages.

source

pub const SELF: ContactId = _

The owner of the account.

The email-address is set by set_config using “addr”.

source

pub const INFO: ContactId = _

ID of the contact for info messages.

source

pub const DEVICE: ContactId = _

ID of the contact for device messages.

source

pub(crate) const LAST_SPECIAL: ContactId = _

source

pub const DEVICE_ADDR: &'static str = "device@localhost"

Address to go with ContactId::DEVICE.

This is used by APIs which need to return an email address for this contact.

source

pub const fn new(id: u32) -> ContactId

Creates a new ContactId.

source

pub fn is_special(&self) -> bool

Whether this is a special ContactId.

Some ContactIds are reserved for special contacts like ContactId::SELF, ContactId::INFO and ContactId::DEVICE. This function indicates whether this ContactId is any of the reserved special ContactIds (true) or whether it is the ContactId of a real contact (false).

source

pub const fn to_u32(&self) -> u32

Numerical representation of the ContactId.

Each contact ID has a unique numerical representation which is used in the database (via [rusqlite::ToSql]) and also for FFI purposes. In Rust code you should never need to use this directly.

source

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

Mark contact as bot.

source

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

Reset gossip timestamp in all chats with this contact.

source

pub(crate) async fn scaleup_origin( context: &Context, ids: &[Self], origin: Origin ) -> Result<()>

Updates the origin of the contacts, but only if origin is higher than the current one.

source§

impl ContactId

source

async fn get_stock_name_n_addr(self, context: &Context) -> String

Get contact name and address for stock string, e.g. Bob (bob@example.net)

source

async fn get_stock_name(self, context: &Context) -> String

Get contact name, e.g. Bob, or bob@exmple.net if no name is set.
