Struct FeatureVariations

pub struct FeatureVariations<'a> { /* private fields */ }
Expand description

FeatureVariations table.

A feature variations table describes variations on the effects of features based on various conditions. That is, it allows the default set of lookups for a given feature to be substituted with alternates of lookups under particular conditions.
