Enum AttributeValue

pub enum AttributeValue<'src> {
    Value(CowStr<'src>),
    Set,
    Unset,
}

The interpreted value of an Attribute.

If the value contains a textual value, this value will have any continuation markers resolved, but will no longer contain a reference to the Span that contains the value.

Variants

Value(CowStr<'src>)

A custom value with all necessary interpolations applied.

Set

No explicit value. This is typically interpreted as either boolean true or a default value for a built-in attribute.

Unset

Explicitly unset. This is typically interpreted as boolean ‘false’.

Trait Implementations

impl<'src> Clone for AttributeValue<'src>

fn clone(&self) -> AttributeValue<'src>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'src> Debug for AttributeValue<'src>

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

Formats the value using the given formatter.

impl<'src> PartialEq for AttributeValue<'src>

fn eq(&self, other: &AttributeValue<'src>) -> 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.
