Returns a duplicate of the value.

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

Performs copy-assignment from source.

Formats the value using the given formatter.

impl Fields for UnderparenElem

type Enum = Fields

An enum with the fields of the element.

fn has(&self, id: u8) -> bool

Whether the element has the given field set.

fn field(&self, id: u8) -> Result<Value, FieldAccessError>

Get the field with the given field ID.

fn field_with_styles( &self, id: u8, styles: StyleChain<'_>, ) -> Result<Value, FieldAccessError>

Get the field with the given ID in the presence of styles.

impl Hash for UnderparenElem

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,
