Enum SubstitutionValue 

pub enum SubstitutionValue {
    Link(LinkId),
    Variable(String),
}

A link reference or named variable in a substitution pattern.

Variants

Link(LinkId)

Exact link reference.

Variable(String)

Variable reference such as $source.

Implementations

impl SubstitutionValue

pub const fn link(link_id: LinkId) -> Self

Creates an exact link reference.

pub fn variable(name: impl Into<String>) -> Self

Creates a variable reference. A leading $ is accepted and stripped.

Trait Implementations

impl Clone for SubstitutionValue

fn clone(&self) -> SubstitutionValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SubstitutionValue

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

Formats the value using the given formatter.

impl PartialEq for SubstitutionValue

fn eq(&self, other: &SubstitutionValue) -> 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.
