pub fn try_normalize_import(
    use_item: &Use,
    style: NormalizationStyle
) -> Option<Use>
Expand description

Normalizes a use item by:

  • Ordering all use trees
  • Merging use trees with common prefixes
  • Removing redundant braces based on the specified normalization style (see NormalizationStyle doc)

Examples:

Using the “Default” normalization style

  • foo::{bar::Qux, bar::{self}} -> foo::bar::{self, Qux}
  • foo::bar::{self} -> foo::bar
  • {foo::bar} -> foo::bar

Using the “One” normalization style

  • foo::{bar::Qux, bar::{self}} -> {foo::bar::{self, Qux}}
  • foo::bar::{self} -> {foo::bar}
  • foo::bar -> {foo::bar}
