Struct imessage_database::tables::chat_handle::ChatToHandle

pub struct ChatToHandle { /* private fields */ }

Represents a single row in the chat_handle_join table.

Trait Implementations

impl Cacheable for ChatToHandle

fn cache(db: &Connection) -> Result<HashMap<Self::K, Self::V>, TableError>

Generate a hashmap containing each chatroom’s ID pointing to a HashSet of participant handle IDs

Example:

use imessage_database::util::dirs::default_db_path;
use imessage_database::tables::table::{Cacheable, get_connection};
use imessage_database::tables::chat_handle::ChatToHandle;

let db_path = default_db_path();
let conn = get_connection(&db_path).unwrap();
let chatrooms = ChatToHandle::cache(&conn);

type K = i32

type V = BTreeSet<i32, Global>

impl Deduplicate for ChatToHandle

fn dedupe(duplicated_data: &HashMap<i32, Self::T>) -> HashMap<i32, i32>

Given the initial set of duplicated chats, deduplicate them based on the participants

This returns a new hashmap that maps the real chat ID to a new deduplicated unique chat ID that represents a single chat for all of the same participants, even if they have multiple handles

type T = BTreeSet<i32, Global>

impl Diagnostic for ChatToHandle

fn run_diagnostic(db: &Connection) -> Result<(), TableError>

Emit diagnostic data for the Chat to Handle join table

Get the number of chats referenced in the messages table that do not exist in this join table:

Example:

use imessage_database::util::dirs::default_db_path;
use imessage_database::tables::table::{Diagnostic, get_connection};
use imessage_database::tables::chat_handle::ChatToHandle;

let db_path = default_db_path();
let conn = get_connection(&db_path).unwrap();
ChatToHandle::run_diagnostic(&conn);

impl Table for ChatToHandle

fn from_row(row: &Row<'_>) -> Result<ChatToHandle>

Serializes a single row of data to an instance of the struct that implements this Trait

fn get(db: &Connection) -> Result<Statement<'_>, TableError>

Gets a statement we can execute to iterate over the data in the table

fn extract( chat_to_handle: Result<Result<Self, Error>, Error> ) -> Result<Self, TableError>

Extract valid row data while handling both types of query errors
