Required Methods

fn into_multi_map_and_lits<K, KF>( self, path_to_key: KF, ) -> Result<(HashMap<K, Vec<(usize, Meta1)>>, Vec<(usize, Lit)>)>

where K: Hash + Eq, KF: Fn(&Path) -> Result<Option<K>>,

fn into_unique_map_and_lits<K, KF>( self, path_to_key: KF, ) -> Result<(HashMap<K, (usize, Meta1)>, Vec<(usize, Lit)>)>

where K: Hash + Eq, KF: Fn(&Path) -> Result<Option<K>>,

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
