Struct Jid

Source

pub struct Jid { /* private fields */ }

Expand description

A struct representing a Jabber ID (JID).

This JID can either be “bare” (without a /resource suffix) or full (with a resource suffix).

In many APIs, it is appropriate to use the more specific types (BareJid or FullJid) instead, as these two JID types are generally used in different contexts within XMPP.

This dynamic type on the other hand can be used in contexts where it is not known, at compile-time, whether a JID is full or bare.

Implementations§

Source §

impl Jid

Source

pub fn new(unnormalized: &str) -> Result<Jid, Error>

Constructs a Jabber ID from a string. This is of the form node@domain/resource, where node and resource parts are optional. If you want a non-fallible version, use Jid::from_parts instead.

§Examples

use jid::Jid;

let jid = Jid::new("node@domain/resource")?;

assert_eq!(jid.node().map(|x| x.as_str()), Some("node"));
assert_eq!(jid.domain().as_str(), "domain");
assert_eq!(jid.resource().map(|x| x.as_str()), Some("resource"));

Source

pub fn into_inner(self) -> String

Returns the inner String of this JID.

Source

pub fn from_parts( node: Option<&NodeRef>, domain: &DomainRef, resource: Option<&ResourceRef>, ) -> Self

Build a Jid from typed parts. This method cannot fail because it uses parts that have already been parsed and stringprepped into NodePart, DomainPart, and ResourcePart.

This method allocates and does not consume the typed parts. To avoid allocation if both node and resource are known to be None and domain is owned, you can use domain.into().

Source

pub fn node(&self) -> Option<&NodeRef>

The optional node part of the JID as reference.

Source

pub fn domain(&self) -> &DomainRef

The domain part of the JID as reference

Source

pub fn resource(&self) -> Option<&ResourceRef>

The optional resource of the Jabber ID. It is guaranteed to be present when the JID is a Full variant, which you can check with Jid::is_full.

Source

pub fn to_bare(&self) -> BareJid

Allocate a new BareJid from this JID, discarding the resource.

Source

pub fn into_bare(self) -> BareJid

Transforms this JID into a BareJid, throwing away the resource.

let jid: Jid = "foo@bar/baz".parse().unwrap();
let bare = jid.into_bare();
assert_eq!(bare.to_string(), "foo@bar");

Source

pub fn is_full(&self) -> bool

Checks if the JID is a full JID.

Source

pub fn is_bare(&self) -> bool

Checks if the JID is a bare JID.

Source

pub fn as_str(&self) -> &str

Return a reference to the canonical string representation of the JID.

Source

pub fn try_into_full(self) -> Result<FullJid, BareJid>

Try to convert this Jid to a FullJid if it contains a resource and return a BareJid otherwise.

This is useful for match blocks:

let jid: Jid = "foo@bar".parse().unwrap();
match jid.try_into_full() {
    Ok(full) => println!("it is full: {:?}", full),
    Err(bare) => println!("it is bare: {:?}", bare),
}

Source

pub fn try_as_full(&self) -> Result<&FullJid, &BareJid>

Try to convert this Jid reference to a &FullJid if it contains a resource and return a &BareJid otherwise.

This is useful for match blocks:

let jid: Jid = "foo@bar".parse().unwrap();
match jid.try_as_full() {
    Ok(full) => println!("it is full: {:?}", full),
    Err(bare) => println!("it is bare: {:?}", bare),
}
