Struct ruma_identifiers::RoomId

pub struct RoomId { /* fields omitted */ }

A Matrix room ID.

A RoomId is generated randomly or converted from a string slice, and can be converted back into a string as needed.

assert_eq!(
    RoomId::try_from("!n8f893n9:example.com").unwrap().as_ref(),
    "!n8f893n9:example.com"
);

Methods

impl RoomId

pub fn new(server_name: &str) -> Result<Self, Error>

This is supported on feature="rand" only.

Attempts to generate a RoomId for the given origin server with a localpart consisting of 18 random ASCII characters.

Fails if the given homeserver cannot be parsed as a valid host.

pub fn localpart(&self) -> &str

Returns the rooms's unique ID.

pub fn server_name(&self) -> &str

Returns the server name of the room ID.
