Enum Inherited 

pub enum Inherited<T> {
    Inherited,
    Specified(T),
}

Represents a property that can optionally be inherited from a parent element.

Variants

Inherited

If inherited, the value of this property is taken from the parent element (transitively). If none of the parent elements have specified a value for this property, the default value is used.

Specified(T)

If specified, this overrides any value from a parent element (transitively) for the same property.

Trait Implementations

impl<T: Clone> Clone for Inherited<T>

fn clone(&self) -> Inherited<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Inherited<T>

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

Formats the value using the given formatter.

impl<T> Default for Inherited<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T> FromStr for Inherited<T>

where T: FromStr,

type Err = ()

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl<T: PartialEq> PartialEq for Inherited<T>

fn eq(&self, other: &Inherited<T>) -> 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.

impl<T: Copy> Copy for Inherited<T>

impl<T: Eq> Eq for Inherited<T>

impl<T> StructuralPartialEq for Inherited<T>
