Function try_normalize_import

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

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}
