Struct ruma_identifiers::UserId

pub struct UserId { /* fields omitted */ }

A Matrix user ID.

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

assert_eq!(
    UserId::try_from("@carl:example.com").unwrap().as_ref(),
    "@carl:example.com"
);

Implementations

impl UserId

pub fn new(server_name: &ServerName) -> Self

This is supported on crate feature rand only.

Attempts to generate a UserId for the given origin server with a localpart consisting of 12 random ASCII characters.

pub fn parse_with_server_name(
    id: impl AsRef<str> + Into<Box<str>>,
    server_name: &ServerName
) -> Result<Self, Error>

Attempts to complete a user ID, by adding the colon + server name and @ prefix, if not present already.

This is a convenience function for the login API, where a user can supply either their full user ID or just the localpart. It only supports a valid user ID or a valid user ID localpart, not the localpart plus the @ prefix, or the localpart plus server name without the @ prefix.

impl UserId

pub fn localpart(&self) -> &str

Returns the user’s localpart.

pub fn server_name(&self) -> &ServerName

Returns the server name of the user ID.

pub fn is_historical(&self) -> bool

Whether this user ID is a historical one, i.e. one that doesn’t conform to the latest specification of the user ID grammar but is still accepted because it was previously allowed.

impl UserId

pub fn as_str(&self) -> &str

Creates a string slice from this UserId

pub fn as_bytes(&self) -> &[u8]

Creates a byte slice from this UserId

pub fn into_string(self) -> String

Converts this UserId into a String

pub fn into_bytes(self) -> Vec<u8>

Converts this UserId into a Vec<u8>
