Struct Union

pub struct Union<L, R> { /* private fields */ }

A combination of two arbitrary LanguageSets into one.

Union implements LanguageSet for a pair of any two LanguageSets. This allows combining multiple sets. The R set acts as the fallback. If a language is requested, first the left set is queried for a match, and only if it fails to provide one the right set will be queried.

The accompanying language type is EitherLang.

Implementations

impl<L, R> Union<L, R>

pub fn new(left: L, right: R) -> Self

Create a new Union set by combining left and right.

pub fn left(&self) -> &L

Get a reference to the left set.

pub fn right(&self) -> &R

Get a reference to the right set.
