Enum ValueRef 

pub enum ValueRef<'a> {
    String(Cow<'a, str>),
    Jid(JidRef<'a>),
}

A decoded attribute value that can be either a string or a structured JID. This avoids string allocation when decoding JID tokens - the JidRef is returned directly and only converted to a string when actually needed.

Variants

String(Cow<'a, str>)

Jid(JidRef<'a>)

Implementations

impl<'a> ValueRef<'a>

pub fn as_str(&self) -> Option<&str>

Get the value as a string slice, if it’s a string variant.

pub fn as_jid(&self) -> Option<&JidRef<'a>>

Get the value as a JidRef, if it’s a JID variant.

pub fn to_jid(&self) -> Option<Jid>

Convert to an owned Jid, parsing from string if necessary.

pub fn to_string_cow(&self) -> Cow<'a, str>

Convert to a string, formatting the JID if necessary. Returns a Cow to avoid allocation when the value is already a string.

Trait Implementations

impl<'a> Clone for ValueRef<'a>

fn clone(&self) -> ValueRef<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for ValueRef<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> Display for ValueRef<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> PartialEq for ValueRef<'a>

fn eq(&self, other: &ValueRef<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
