Struct ruma::user_id::UserId

source ·
pub struct UserId(/* private fields */);
Expand description

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(), "@carl:example.com");

Implementations§

source§

impl UserId

source

pub fn as_str(&self) -> &str

Available on crate feature events only.

Creates a string slice from this UserId.

source

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

Available on crate feature events only.

Creates a byte slice from this UserId.

source§

impl UserId

source

pub fn parse(s: impl AsRef<str>) -> Result<OwnedUserId, Error>

Available on crate feature events only.

Try parsing a &str into an OwnedUserId.

The same can also be done using FromStr, TryFrom or TryInto. This function is simply more constrained and thus useful in generic contexts.

source

pub fn parse_box( s: impl AsRef<str> + Into<Box<str>> ) -> Result<Box<UserId>, Error>

Available on crate feature events only.

Try parsing a &str into a Box<UserId>.

The same can also be done using FromStr, TryFrom or TryInto. This function is simply more constrained and thus useful in generic contexts.

source

pub fn parse_rc(s: impl AsRef<str> + Into<Rc<str>>) -> Result<Rc<UserId>, Error>

Available on crate feature events only.

Try parsing a &str into an Rc<UserId>.

source

pub fn parse_arc( s: impl AsRef<str> + Into<Arc<str>> ) -> Result<Arc<UserId>, Error>

Available on crate feature events only.

Try parsing a &str into an Arc<UserId>.

source§

impl UserId

source

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

Available on crate features events and rand only.

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

source

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

Available on crate feature events only.

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.

source

pub fn parse_with_server_name_rc( id: impl AsRef<str> + Into<Rc<str>>, server_name: &ServerName ) -> Result<Rc<UserId>, Error>

Available on crate feature events only.

Variation of parse_with_server_name that returns Rc<Self>.

source

pub fn parse_with_server_name_arc( id: impl AsRef<str> + Into<Arc<str>>, server_name: &ServerName ) -> Result<Arc<UserId>, Error>

Available on crate feature events only.

Variation of parse_with_server_name that returns Arc<Self>.

source

pub fn localpart(&self) -> &str

Available on crate feature events only.

Returns the user’s localpart.

source

pub fn server_name(&self) -> &ServerName

Available on crate feature events only.

Returns the server name of the user ID.

source

pub fn is_historical(&self) -> bool

Available on crate feature events only.

Whether this user ID is a historical one.

A historical user ID is one that doesn’t conform to the latest specification of the user ID grammar but is still accepted because it was previously allowed.

source

pub fn matrix_to_uri(&self) -> MatrixToUri

Available on crate feature events only.

Create a matrix.to URI for this user ID.

§Example
use ruma_common::user_id;

let message = format!(
    r#"Thanks for the update <a href="{link}">{display_name}</a>."#,
    link = user_id!("@jplatte:notareal.hs").matrix_to_uri(),
    display_name = "jplatte",
);
source

pub fn matrix_uri(&self, chat: bool) -> MatrixUri

Available on crate feature events only.

Create a matrix: URI for this user ID.

If chat is true, a click on the URI should start a direct message with the user.

§Example
use ruma_common::user_id;

let message = format!(
    r#"Thanks for the update <a href="{link}">{display_name}</a>."#,
    link = user_id!("@jplatte:notareal.hs").matrix_uri(false),
    display_name = "jplatte",
);
