integrator: u16

Implementations

impl Jid

pub fn new(user: &str, server: &str) -> Jid

pub fn pn(user: impl Into<String>) -> Jid

Create a phone number JID (s.whatsapp.net)

pub fn lid(user: impl Into<String>) -> Jid

Create a LID JID (lid server)

pub fn status_broadcast() -> Jid

Creates the status@broadcast JID used for status/story updates.

pub fn group(id: impl Into<String>) -> Jid

Create a group JID (g.us).

pub fn newsletter(id: impl Into<String>) -> Jid

Create a newsletter (channel) JID (newsletter server).

pub fn pn_device(user: impl Into<String>, device: u16) -> Jid

Create a phone number JID with device ID

pub fn lid_device(user: impl Into<String>, device: u16) -> Jid

Create a LID JID with device ID

pub fn is_pn(&self) -> bool

Returns true if this is a Phone Number based JID (s.whatsapp.net)

pub fn is_lid(&self) -> bool

Returns true if this is a LID based JID

pub fn user_base(&self) -> &str

Returns the user part without the device ID suffix (e.g., “123:4” -> “123”)

pub fn with_device(&self, device_id: u16) -> Jid

Helper to construct a specific device JID from this one

pub fn actual_agent(&self) -> u8

pub fn to_non_ad(&self) -> Jid

pub fn matches_user_or_lid(&self, user: &Jid, lid: Option<&Jid>) -> bool

Check if this JID matches the user or their LID. Useful for checking if a participant is “us” in group messages.

pub fn normalize_for_prekey_bundle(&self) -> Jid

Normalize the JID for use in pre-key bundle storage and lookup.

WhatsApp servers may return JIDs with varied agent fields, or we might derive them with agent fields in some contexts. However, pre-key bundles are stored and looked up using a normalized key where the agent is 0 for standard servers (s.whatsapp.net, lid).

pub fn to_ad_string(&self) -> String

pub fn device_eq(&self, other: &Jid) -> bool

Compare device identity (user, server, device) without allocation.

pub fn device_key(&self) -> DeviceKey<'_>

Get a borrowing key for O(1) HashSet lookups by device identity.

Trait Implementations

impl Clone for Jid

fn clone(&self) -> Jid

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Jid

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for Jid

fn default() -> Jid

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Jid

fn deserialize<__D>( __deserializer: __D, ) -> Result<Jid, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Jid

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl FromStr for Jid

type Err = JidError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Jid, <Jid as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for Jid

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl JidExt for Jid

fn to_protocol_address(&self) -> ProtocolAddress

Build a ProtocolAddress for Signal session store lookups. The device_id is always 0 — WhatsApp encodes the device in the name.

fn to_signal_address_string(&self) -> String

Returns the Signal address string in WhatsApp Web format. Format: {user}[:device]@{server}

fn to_protocol_address_string(&self) -> String

Returns the full protocol address string including the device_id suffix. Format: {signal_address_string}.0 This is equivalent to to_protocol_address().to_string() but avoids the intermediate ProtocolAddress allocation — one String instead of two.

impl JidExt for Jid

fn user(&self) -> &str

fn server(&self) -> &str

fn device(&self) -> u16

fn integrator(&self) -> u16

fn is_ad(&self) -> bool

fn is_interop(&self) -> bool

fn is_messenger(&self) -> bool

fn is_group(&self) -> bool

fn is_broadcast_list(&self) -> bool

fn is_status_broadcast(&self) -> bool

fn is_bot(&self) -> bool

fn is_newsletter(&self) -> bool

fn is_hosted(&self) -> bool

Returns true if this is a hosted/Cloud API device. Hosted devices have device ID 99 or use @hosted/@hosted.lid server. These devices should be excluded from group message fanout.

fn is_empty(&self) -> bool

fn is_same_user_as(&self, other: &impl JidExt) -> bool

impl PartialEq for Jid

fn eq(&self, other: &Jid) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Jid

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<String> for Jid

type Error = JidError

The type returned in the event of a conversion error.

fn try_from(value: String) -> Result<Jid, <Jid as TryFrom<String>>::Error>

Performs the conversion.

impl Eq for Jid

impl StructuralPartialEq for Jid
