LID (Local ID) mapping types and utilities.

LID mapping is used to convert between Phone Number (PN) JIDs and Local ID (LID) JIDs for WhatsApp's privacy features. This allows users to communicate without exposing their phone numbers.

t()

Functions

construct_device_jid(user, device, domain)

decode_jid(jid)

Decodes a JID into its components.

hosted_pn_user?(jid)

Checks if a JID is a hosted phone number user.

lid_user?(jid)

Checks if a JID is a LID user.

new(pn, lid)

Creates a new LID mapping.

normalize_user(jid)

Normalizes a JID to its user part.

pn_user?(jid)
